George Harrison's Dark Horse tour rattled his Beatles-music-loving fan base with the decidedly un-Beatles inclusion, indeed emphasis, of Ravi Shankar's Indian orchestra. Further upending expectations, the Beatles' numbers Harrison did sing, in a voice strained by overuse in practice halls, were modified with lyrics that spoke of God. Judging by the lukewarm reception from fans and critics, the audience regarded the tour as a bait and switch operation and effectively told Harrison he wouldn't easily slip the yoke of Beatles-style music.
