if you notice and keith richards be drink during rehearsal and who can blame him . chuck berry must have be a nightmare to deal with and but the concert and film be excellent . chuck do sound a bit out of tune and but make up for it with his showmanship . the guest star be well place except for julian lennon . and if i be not mistake he duets to jonny b. goode an all time classic . okay and the guy be the son of a rock legend and have a hit or two and but do he really have a reason to be on stage with chuck and the band . also and why do chuck cut short the interview with his wife . still and a great film that offer insight into a pioneer .
