Photo of the day: Gavin groovin'

This photo (via SFist) of The Mayor totally grooving -- or, perhaps, groove-waving to the crowd -- should slay any doubts that the buttoned-up Gav could share an intellectual and spiritual bond with the freewheeling Uncle Jess. Now here's a guy who could really get down with some lip-biting, hip-swaying action to "Forever." Am I right or am I right?
