It sounds to me like you probably ARE overplaying and just don't care. If you overplay on Mustang Sally and lose the groove you deserve to lose the gig. IMO.....I auditioned a while back for a guy who had a little event band and some of the feedback was that he thought I played to much on some stuff....I've played Mustang Sally about 949,656 times and I am not playing that as is. Sorry, ain't gonna happen....
