This clip epitomises the culmination of the boys totally and utterly conquering America. Watch John, and to some extent, George completely 'losing it' after what must have been a gruelling and strength sapping schedule. It's as if they knew at this point that they were the greatest band in the world. And, of course, they were. The rest, as they say, is history.
Not seen this included yet, my apologies if it has been. The out-tatke quad of Lennon on R'n'R Circus. John mic cuts out towards the end, so that's probably why it wasnt used. Claptons guitar is heavier than the more well known version.
Great video and one of my favourite Beatle tracks. Which is odd really because if there was ever a style that The Beatles where weak in it was definitely the blues. However the version on The White album is great (with the exception of the guitar solos!) and showed they could play in any style they chose to when they put their minds to it but they where terrible jammers (e.g. 12 bar original). The rock 'n' roll circus version works so well because it's a gift to the likes of Clapton and Mitchell (it would have been even better with a proper bass player on it i.e. Bill Wyman).
Incidentally I don't think lennons mic did cut out at the end. He was trying to recreate the album version by not singing into the mic. They probably didn't make a lot of use of this version because he fluffed the words a few times in the last verse.
