Visible crew/equipment: When June performs Juke Box Blues there is a shot on the stage towards the audience and a steadycam operator can be seen on the right side of the screen. (00:45:18)
Factual error: When Cash overhears Elvis recording Elvis Presley recording Milk cow blues, there are drums on the record. Elvis did not use a drummer when this record was made.
Continuity mistake: During the first tour when all the guys are on the stage drinking, June throws 4 beer bottles. The last one is thrown twice because there were only 3 lying there.
Continuity mistake: When John wakes up with Waylon singing, the left side of his collar is rumpled. When he gets up to use the telephone it's straightened out.
Continuity mistake: At the first concert with Jerry Lee, towards the end of his song his white scarf disappears.
