the others; Starr's Ringo (1973) was the only album to include compositions and performances by all four ex-Beatles, albeit on separate songs. With Starr's participation, Harrison staged the Concert for Bangladesh in New York City in August 1971. Other than an unreleased jam session in 1974, later bootlegged as A Toot and a Snore in '74, Lennon and McCartney never recorded together again. Two double-LP sets of the Beatles' greatest hits, compiled by Klein, 1962–1966 and 1967–1970, were released in 1973, at first under the Apple Records imprint. Commonly known as the "Red Album" and "Blue Album", respectively, each has earned a Multi-Platinum certification in the US and a Platinum certification in the UK. Between 1976 and 1982, EMI/Capitol released a wave of compilation albums without input from the ex-Beatles, starting with the double-disc compilation Rock 'n' Roll Music. The only one to feature previously unreleased material was The Beatles at the Hollywood Bowl (1977); the first officially issued concert recordings by the group, it contained selections from two shows they played during their 1964 and 1965 US tours. The music and enduring fame of the Beatles were commercially exploited in various other ways, again often outside their creative control. In April 1974, the musical John, Paul, George, Ringo ... and Bert, written by Willy Russell and featuring singer Barbara Dickson, opened in London. It included, with permission from Northern Songs, eleven Lennon-McCartney compositions and one by Harrison, "Here Comes the Sun". Displeased with the production's use of his song, Harrison withdrew his permission to use it. Later that year, the off-Broadway musical Sgt. Pepper's Lonely Hearts Club Band on the Road opened. All This and World War II (1976) was an unorthodox nonfiction film that combined newsreel footage with covers of Beatles songs by performers ranging from Elton John and Keith Moon to the London Symphony Orchestra. The Broadway musical Beatlemania, an unauthorised nostalgia revue, opened in early 1977 and proved popular, spinning off five separate touring productions. In 1979, the band sued the producers, settling for several million dollars in damages. Sgt. Pepper's Lonely Hearts Club Band (1978), a musical film starring the Bee Gees and Peter Frampton, was a commercial failure and an "artistic fiasco", according to Ingham. Accompanying the wave of Beatles nostalgia and persistent reunion rumours in the US during the 1970s, several entrepreneurs made public offers to the Beatles for a reunion concert. Promoter
