Honey and Clover song similar to Bon Bon Bereppa?

I'm trying to find a song from the anime Honey and Clover that sounds like Bon Bon Bereppa (http://www.youtube.com/watch?v=toreRBOjIxE) but isn't so jazzy/musical. It just starts off with guys kind of slowly singing the bon bon part. Does anyone know where I can find it/ what it's called?
