Sing（唱吧），原本是由喬·拉波索為美國著名兒童節目《芝麻街》而創作的主題歌。
這首歌曲最初由《芝麻街》節目組的工作人員，以及節目中的經典角色諸如Muppet布偶、大鳥等進行演唱。
歌曲清新歡快的曲風以及琅琅上口的歌詞為當時節目的小觀眾們所喜愛。


歌詞：

Sing, sing a song.
Sing out loud.
Sing out Strong.
Sing of good things not bad.
Sing of happy not sad.

Sing, sing a song.
Make it simple to last
Your whole life long.
Don't worry that it's not
Good enough
For everony else to hear.
Just sing, sing a song.

La la la la...

Sing, sing a song.
Let the world sing along.
Sing of love there could be.
Sing for you and for me.

Sing, sing a song.
Make it simple to last
Your whole life long.
Don't worry that it's not
Good enough
For everony else to hear.
Just sing, sing a song.

La la la la....
