The Cadillac Daddys started as a jam session during a MINI Cooper Rally.  Jackman and Scotty thought it would be cool to play during the lunch break so they broke out their amps in the parking lot, plugged into Jackman’s MINI and started wailing. 
A few months later Scott volunteered to organize the music for a block party.  At this same moment Jackman had the divine inspiration to form a Rockabilly band.  An online ad found Sticks Taylor to fill out the trio.  The block party performance a mere two weeks later was an unqualified success and led to a summer of outdoor performances.
One night a a real gone tenor player named Fat Lip Evans sat in with the trio. The sound stuck; the rest was history.
