Rock-A-Bye Baby

Rock-A-Bye Baby is a nursery rhyme, sung by Marge Simpson in The Tracey Ullman Show short, "Good Night". She sung it to Maggie Simpson, when putting her to sleep and it has become the first musical number in The Simpsons series.

In the Season 28 episode, "Looking for Mr. Goodbart", The Simpsons opened with a celebration of their 30 year anniversary of being on television, by showing a brief clip of the first ever Simpsons short before the episode, containing the scene with Marge singing this song to Maggie, helping her go to sleep.

Lyrics
Rock-A-Bye Baby In the treetop. When the wind blows the cradle will rock. When the bough breaks the cradle will fall and down will come baby, cradle, and all.
