Hm, you're going to make me come up with more details, aren't you?<br/><br/>Let's see... one of the band members, the big, strong looking one, is showing off just how strong he is.  Mainly just stupid bar bets.  The more slender-looking one is chatting with a few other people, likely swapping stories of various things (all probably very embellished), they're laughing quite a bit.  The last one, the one that Damian didn't see at first, seems to be more serious, still drinking but not as much as the other band members.
