i did not know that there was a film for sgt pepper's lonely heart's club band and no, i did not see it. i did see other beatles films like a hard day's night, yellow submarine, help! and magical mystery tour (did not get to see let it be yet) though
i just checked imdb and it looks like, if i am looking at the right version, the sgt pepper movie does not seem to get good vibes. anyways have fun watchin'
