What are the chances of meeting the performer after saturday night live?

I'm going to be visiting saturday night live and i really want to try and meet the singer who performed after the show. Does anyone know my chances of that happening and/or where i should go to make this happen? Also, i dont have tickets yet but im going to wait on the stand-by line that morning. Are my chances greater if im actually in the audience? Thanks soooo much!What are the chances of meeting the performer after saturday night live?
Your only chance of meeting the singer is if you know where the after-party is, if there is one.
