“A triumph of audacity and bad taste.”

All This and World War II is a 1976 musical documentary that mixes World War II newsreels and movie clips with Beatles covers. Looks like Hitler disapproved. Wikipedia; hard to believe Terry Gilliam passed on this. Reviews, extensive case study, and interviews.
Even by the standards of the studio which dropped such oddities as “Myra Breckinridge,” “Beyond the Valley of the Dolls” and “The Rocky Horror Picture Show,” this flick was more than peculiar.

You can watch the entire movie (parts one, two, three, four, five, six, and seven) or just watch Frankie Valli’s “A Day in the Life” (D-Day), Henry Gross’s “Help!” (North Africa), Wil Malone & Lou Reizner’s “You Never Give Me Your Money” (Liberation of Europe), Keith Moon’s “When I’m 64” (US troop ships in the Pacific), The Bee Gees’ “Golden Slumbers” (The Blitz; what is it with them and horrible Beatles movies?), Elton John’s “Lucy in the Sky With Diamonds” (air war/kamikazes), and the London Symphony Orchestra’s “The End.” (The LSO did most of the music in the film.)
The Bee Gees also do “She Came In Through The Bathroom Window” and “Sun King” (Japan moves toward Pearl Harbor), The Brothers Johnson do “Hey Jude” (Stalin and the Red Army), Ambrosia does “Magical Mystery Tour” (Germany invades Poland), Leo Sayer does “I Am the Walrus” (Pearl Harbor attack) and “Let It Be” (internment of Japanese Americans), Jeff Lynne does “Nowhere Man” (Mussolini), Helen Reddy does “The Fool on the Hill” (Hitler), Peter Gabriel does “Strawberry Fields Forever” (his first solo song; Chamberlain appeases Hitler; “living is easy with eyes closed”), Rod Stewart does “Get Back” (as Nazis march backwards in reversed footage), and Tina Turner does “Come Together.” And that’s not all! (Somehow they avoided the temptation of matching U-Boats with “Yellow Submarine.”)
You can buy the CD if you dare. AMG soundtrack review.
The Bee Gees also recorded “She’s Leaving Home,” “Lovely Rita,” and “Lucy in the Sky with Diamonds,” and ofcourse Diamond Diamond, but those recordings weren’t used in the film.
