No sign of Pete tho.
Pete is somewhere in the shadow, but this was definitely filmed in 1961. look, first of all look at their hairdo and clothes. The Beatles already signed the contract with (I don't remember, which) the music company in 1962. so you wanna say they still did those concerts in hamburg clubs in 1962, though they already had to record "please please me"?. that source is probably wrong.
this is from 1961 (btw George holds the same "gretsch gentleman (black)" as in the video, I dunno if George ever used a gretsch in 1962. Paul's also hold the same hofner and John holds the same "rickenbacker (brown)")
and this is from 1962:
see a difference?
