Song...If Cupid Had A Heart??? PLEASE HELP!

There is a song in this movie in the pizza parlor where the scene is where JC and Joey are throwing dough back and forth at each other. In the background is a song with lyrics - "if cupid had a heart he would make me fall...in no time at all" or something like that. It's not on the soundtrack or listed in the credits, I've exhausted every single search for this and come up with nothing! I am desperate to find out information on this song as it also appeared in an episode of King of the Hill at Kahn Jr's slumber party. Any help is greatly appreciated. Thanks!!!
