Here's something interesting: shown are Beatles Ringo Starr, John Lennon, and Paul McCartney, as well as the late Mrs. Maureen Starkey and The Masque Of The Red Death heroine actress and former McCartney main squeeze Jane Asher at a costume party, but amazingly not for Halloween-- December 21, 1967 --for the upcoming telefilm, the ill-fated "Magical Mystery Tour".
By this time after all the successes and benchmarks set by Messrs. Lennon, McCartney, Harrison, & Starr, the Beatles apparently could do no wrong-- until "Magical Mystery Tour" that is...
Even though the music was as usual up to the high, ahem, standards set by "Revolver" and "Sgt. Pepper's", the critics mercilessly lambasted the movie because they just didn't get it.
Essentially McCartney's version of the San Francisco adventures of Ken Kesey and The Merry Pranksters, albeit translated into the Queen's English, it really had no plot or subplot, which as you know was/is a cardinal sin insofar as conventional movie critics are concerned.
Plus you either had to be a Beatles devotee or acidhead, or maybe some good hash would do.
But careerwise, "Magical Mystery Tour" unlike "Sgt. Pepper's" was a Major Bummer.
In any case this was also the infamous event where Beatle Lennon was allegedly flirting and dancing with Beatle Harrison wife the beauteous Patti, object of many a Rock Star's wet dream.
