this be an enjoyable movie . it very realistic to the wonderful world of music i have be there and do that . it show a human element in each character and the realism that nobody be perfect . these amateur musician weren not all that bad player . cleavon little character and marshall tucker and be play very well . marshall be no saint himself . here he be get pay to do a job and he give these guy a hard time about everything in the van on the way up there . you do not bite the hand that fee you . i do find it hard to believe that a player with the jazz experience he have and claim he do not know any of the dixieland tune . he have a tremendous sense of predict chord change to tune he do not know . not common and but not unheard of either . he deliver a true and harsh message at the end of the movie when he tell the clarinet player and it not a religion and devotion be not enough . on that level and he be correct and although i think the clarinet player could have handle the job . he be practice his butt off and vocal accompaniment music be not that hard to read . very enjoyable movie .
