I just got this off ebaY steve-O. Mine is VHS. Yeah, the visual quality is definitely C-, like trying to view it with an awful nearsightedness condition! I complained to my seller, and he responded that it's the best that one is going to find anywhere, and your statement bears that out. The sound is quite good though!
I pretty much agree with you on your overall assessment, but I'll have to listen to Britton on drums again, I thought he was pretty good, very aggressive. There is that one scene where Linda complains about the drums coming in late, but it sounded to me like she was just picking on him. Wouldn't that be a crapper, to land a gig playing with Paul, only to find that his wife thinks you're a creep? Britton's later comment on his being ousted indicated that it was because he wasn't into getting loaded, so he was like a party pooper. Who knows? That sounds like sour grapes too.
Jimmy was was shreddin' pretty good, I was a lot more impressed with him on this than I was with him on the records.
