|Homer's Barbershop Quartet||
- The rooftop concert which the Be Sharps performed on the rooftop of Moe's Tavern at the end of the episode is clearly a parody of the January 30, 1969 Beatles rooftop concert which was performed on the rooftop of the group's Apple Corps studio in London, England. Guest star George Harrison was a member of The Beatles, and his line "it's been done" was likely a reference to this concert. His snub of the Be Sharps reunion also perhaps hinted his years long real-life disdain for his ex-bandmates to reunite under The Beatles name. In the 1970s. Harrison even assisted legendary British comedian Eric Idle in mocking his former band with the creation of a Beatles spoof band called The Rutles. In 1978, two years before ex-Beatle John Lennon's 1980 murder, The Rutles starred in a mockumentary BBC television film called All You Need Is Cash, which parodied, among other things, the 1969 Beatles rooftop concert.
- Ironically, Homer's line during the end credits, "I'd like thank you on behalf of the group and I hope we passed the audition," were the exact words John Lennon said during the version of Get Back which was recorded not for the version of the song which was released as a single, but instead as a song which was included on the group's album Let It Be. This album version of Get Back was the also finale song which was performed during the 1969 Beatles rooftop concert.https://books.google.com/books?id=1CAvwZPKTkoC However, in contrast to the band's usual Lennon-McCartney songwriting partnership, Homer's Harrison was more instrumental than Lennon was for helping Get Back songwriter and fellow Beatle Paul McCartney give the song its title, as McCartney agreed to give the song its title after its words were mentioned in Harrison's song "Sour Milk Sea," and also rearranged Harrison's "Get back to where you should be" lyrics into Get Back's frequent chorus "get back to where you once belonged." Ironically, the word "Mo" was also used during the Let It Be version of Get Back as well. As a result of Ringo Starr's then-wife Maureen baring the nickname "Mo," Paul McCartney included the quip "thanks Mo" before Lennon said the album version's ending line.https://www.songfacts.com/facts/the-beatles/get-back
- The way Lovejoy used the B-Sharps to raise church money bears resemblance to conspiracy theories surrounding Billy Graham's use of at times secular-themed singers such as Johnny Cash to raise money for his Billy Graham Evangelical Association. Lutheran historian Martin E. Marty was known to question Graham's methods of raising money. https://www.wsj.com/articles/SB10001424127887324328204578569253573107528
- Principal Skinner recognizes an old prison helmet of his from Vietnam with the number '24601'; this is the number tattooed on Jean Valjean in Les Misérables, and his only identification. The same number is also Sideshow Bob's prison number in Black Widower, and Marge's in Marge in Chains.
- While rummaging through a box labeled "All items 5¢", Homer comes across some very expensive if not priceless collector items including what appears to be an original signed Declaration of Independence, Action Comics #1, Inverted Jenny stamps, and a Stradivarius violin.

- Apu's new name (de Beaumarchais) is French for 'of the good market', an obscure reference to the Kwik-E-Mart.

The Take Three couch gag shows The Simpsons once again colliding; this time they explode. The Take Three gag was reused in "Homer the Vigilante" and "Secrets of a Successful Marriage". In syndication, only the Take One gag is used.
- A deleted scene of this episode showed Skinner going back to his mother. She asks him if he was with a woman, he says no, then she asks for a bath, followed by mad laughing and a close-up of their Psycho-parody house. This is the first time Skinner would be involved in a knock-off joke based on the movie Psycho.

This program is famous for opening one of Capone's secret vaults, only for them to discover there was nothing inside it.
- When winning the Grammy, Barney mentions he is a fan of David Crosby, only to express confusion that he was a singer as well. This implies that Barney was a fan of David Crosby's history of alcohol and drug abuse.

- The swap meet is in Springfield, yet when the family sedan gets a flat tire, the family is in a desert, despite their house also being in Springfield.
- Baby Lisa says that Homer and the Be Sharps, at the Grammys, "beat Dexy's Midnight Runners." The episode is set in 1985. DMR's only U.S. hit was "Come On Eileen," which topped the charts in 1983, so the latest they most likely would have been considered for any sort of music award would be 1984.
- When Homer returns to the Power Plant, he returns to a role as Safety Inspector, which he was not promoted to until 1989 in "Homer's Odyssey".
- In the final scene, The Human Fly's glove changes color a few times between red and white.

- The cover of "Bigger Than Jesus", The Be-Sharps second album, features the group walking on water. It is a direct parody of the art on The Beatles album Abbey Road. The album's title is also a reference to a controversial statement made by John Lennon. Unlike the Beatles however, no visible fallout is shown from the "bigger than Jesus" comment, which put the Beatles in rough waters.
- The Meet The Be Sharps album name and cover is similar to those of the Beatles' first official (second actual) U.S album Meet The Beatles. The cover is also similar to that of the Beatles' second British album With The Beatles.
- Barney's girlfriend is similar to John Lennon's girlfriend Yoko Ono, whom many Beatles fan hold responsible for the band breaking up.
- Barney's looks before they break up is similar to how John Lennon looked before the Beatles broke up. The break up of the Beatles is similar to this as they broke up due to not wanting to change their style.

- The band's manager, Nigel is based on Brian Epstein who was the Beatles' manager from the 24th January 1962 to his death on the 27th August 1967.
- Nigel telling Homer to keep his marriage a secret is similar to Brian Epstein advising John Lennon to do the same with his marriage to Cynthia Powell.
- Principal Skinner's reputation as the "funny one" is an ironic reference to George Harrison's reputation as the "Quiet Beatle."
- When Barney plays his song when he says of taking the quartet to a new direction, it starts of with his girlfriend saying "number eight" followed by Barney's burp repetitively. This is similar to the start of "Revolution 9", where you hear an unknown announcer say "number nine" repetitively.
- Scene where the Be Sharps are greeted at New York JFK Airport by the fans and press is a reference to the reception the Beatles received when they arrived at JFK on the 7th February 1964 for their appearance on the The Ed Sullivan Show on the 9th February 1964 and their first tour of the US before returning home to the UK on the 22nd February 1964.
