The guys in this Octet are:"Dave, Ben, Jerome, Andy, Jason, (solo by Brandon) missing, David and Aaron." Not to be a braggart, but I think my first guess was pretty good for a somewhat educated guess.
Behold: Slightly Older Oldtet than we are used to! The guys are opening for Artists in Resonance, a mixed a cappella group from Berkeley. The guys, from left to right are...uh, I'm not sure who the first guy is. Second is Ben Sae-Tang (who sang the Tenor 2 part in this Octet), Jerome MC in the glasses (o my heck - LOVE!), not sure who the 4th guy is, and Jason Mabie on the end. The soloist is...um, not sure, but I think it's Brandon, the missing Octo-Dude from '03. That's just a wild stab in the dark, though. I love the song! Well done, Octet!
