Lyrics
Molly: Oh, my. These are the best instruments, the best gifts anyone could ever want. I love them and I love all of you, my new Sesame Street neighbors, my new friends. Come on, friends, let's sing.

Everyone: La la la la la la la la la la la La la la la la la la Sing Sing a song Sing out loud Sing out strong

George Pig: Come on, everyone! Sing along!

Everyone: Sing of good things, not bad Sing of happy, not sad
