ETA: I got an email back, and it is, indeed, the same guy. So I can officially say I knew the guy who does the music for Lost, among other things. Cool, no?Last year I mentioned that I might have known
Michael Giacchino back when I was in college. He's the guy who does music for Lost, among other things.
I'm 98% sure it is the same guy, based on this photo

(The quality sucks, but you can get a general idea)He's the beardless one.
I've compared it to the photos on his website, and it seems to be a match. I emailed him once before, but never heard, so I tried again. I just want him to respond so I can know for sure, because it's no fun saying "I
think I know this famous guy."
He was friends with this guy I was in college with, and when they were seniors in High School they actually made a full length movie that was quite good. Michael was the star. He visited our school a few times, and we hung out during Spring Break because Patrick and Michael lived not too far from me. It is possible we all went to see Star Trek IV together, but I can't remember for sure.
Anyway. I hope he responds this time. It's driving me mad. Every time I see his name on Lost I think, "I knew him! I think. Maybe. Yeah, has to be the same guy. Right?" Like I don't have enough mysteries to deal with on Lost.
