You assume that hey you've been playing in a band for a while now, you could remember the songs from way back in June and in the recording studio sessions. You choose to be irresponsible and play video games with the other three band members. The manager calls about the show tonight and whether or not you have practiced the new material.

YOU EITHER

Bail out on the show and forget about your fans.

Fess up and let him know that you guys didn't practice.
