 Eric Idle mentions in his "memoir" available on the DVD what the  actual Beatles thought of the film. According to him, George  Harrison was very supportive and encouraged him, Paul McCartney was  disapproving at first but relented when he found that Idle grew up  near Liverpool (though his wife Linda always loved it), Ringo Starr  said that he enjoyed it "after 1968", and John Lennon (along with  Yoko Ono) adored it.
