a) i dunno. big bushy hair looking guy. i saw him from the back mostly. and i've never seen a pic of any of them except the one you posted. but they were right next to each other at the wilco concert the night before. so my buddy's buddy said hi.
b) the whole movie thing was just a joke because he (my friend) was like 'yeah i was right beside you at the wilco concert last night, i really like your tunes man' and bss dude was like 'why didn't you say anything?' and he was all like 'i dunno.. thought it would be kinda strange.. didn't want to infringe on your personal space' (bss dude was there with his girlfriend) and bss dude was like 'no man.. if you ever see me on the street say hi! then we can chat, get each other's numbers, become friends, and go see a movies together, it's that kinda thing.' or something like that. any rate.. seems like the guy was a really cool friendly down to earth type fellow at any rate.
