Something to sing about

Joss Wheadon?

I have just seen a phrase from Buffy The Vampire Slayer's musical episode show up in a song by the band Paramore and have also seen it other places. I am curious if Joss originated it or it is older than that. The phrase is "Something to sing about" like, "I need something to sing about", indicating that the singer needs something to make them feel/happy. I am almost certain it is not a Joss original, but does anyone know where it did come from?
