I'll take a wild, wild guess....
Given the length of the hair on the guys - they could be musicians in a rock band photo shoot. Not for an album cover (too riske), but just doing a beatles type thing for photographers, you know - clowning around. Maybe the chick(s) are girlfriends. What band would it be? Anyway, I gave it my best shot....
There is really only one pic - the two below are just blown up from the first group shot.
I think its a rock band
