Mame-Bobby Darin

Fifties rocker Bobby Darin was a chameleon, reinventing himself first as a surprisingly good actor, then as a finger-snapping Sinatra-style mainstream singer in suit and tie (and toupee). That's where we find him here in '66. After this he was briefly a hippieish folksinger before finally returning all-out into lounge-singer mode for his own TV variety series briefly before his early passing.
