Yarn and a contest

It's been a while since I had a contest, so here it is. I need help with something that is driving me crazy.

Last fall ABC had a commercial on the air for their Thursday line-up, and there was a song whose lyrics said something "Come on over" - meaning switch to ABC on Thursday.

I can't find that song on iTunes for the life of me - of course I can't, I do not know the name of the song and who sings it.

Anybody?

I'll draw a name among the right answers and the prize will be something from my stash.
