Look at his comments and what
Bane71 quoted; this is most likely going to have two parts. I don't know how much he is going to go with on the first part. He could take it up to when they are introduced on stage, play the first song, cut it to DLC if that's his plan, or play all the way out. But as you can see, that was his comment.
If he plays the first part out, will that first part spin off into something else, like a bar corruption scene similar to the art class, and could that be DLC. I don't know.
