Actually Urza, You're partly right.
It's a Little Steven song called Come To Me playing and it was added as a little joke for the hardcore fans, like myself. Rare because they have never really done anything like that before to insinuate who these actors really are on the show. But none-the-less, fun. (Little Steven is Silvo Dante, who is also Stevie Van Zandt in real life.)
Chase must have just been having a little fun.
The Doc
And you liar, teller of tall tales: you trample all the Lord's commandments underfoot, you murder, steal, commit adultery, and afterward break into tears, beat your breast, take down your guitar and turn sin into a song. Shrewd devil, you know very well that God pardons singers no matter what they do, because he can simply die for a song.
