oh and by the way, to explain why david and megan were there:
lead singer of ezra, kevin griffin cowrites songs for a slew of artists (including david and megan... and howie day). the concert that night was ezra's annual charity benifit in new orleans and they always ask some of their celeb buddies (usually people who kevin has helped with songwriting) to join them that night.
johnathan silverman was there too (weekend at bernies anyone?) and ryan cabrera (dude needs to take it easy on the hair gel. just saying).
