After the Beatles had retired from touring in the mid-'60s, Paul McCartney came up with "Sgt. Pepper’s Lonely Hearts Club Band," a new song about an Edwardian era military band. The song became an entire album. Sgt. Pepper, the 1967 Beatles LP, is considered one of the greatest rock albums of all time. The movie based on it, featuring a cast of then-popular musicians, was a flop at the box office and remains notorious as one of the great fiascos of cinema.

"Like a box of candy left on the beach, this movie is a gooey, sugary mess," wrote a TV Guide reviewer in 1978.
