There's this tune playing in an episode of Third Watch which I'm trying to find, desperately. There's only one lyric I'm able to hear and it goes something like: "Come on y'all" unless I'm completely mistaken.

Song in question (http://www.youtube.com/watch?feature=player_detailpage&v=t-6qvqbcjWA#t=152s)

I have provided a link to the point in this episode where the song starts playing. Any help would be appreciated, thanks in advance!
