What revolution inspired the Beatles song “Revolution”?
As per Wikipedia: This was the first overtly political song the Beatles recorded, reflecting the shift in Lennon’s 1967 creative focus on psychedelia, LSD, and Transcendental Meditation, which had collapsed in the wake of the Beatles’ February-April 1968 trip to India, Lennon’s involvement with politicially-oriented artist Yoko Ono, and the growing social upheavals of 1968. McCartney was initially uneasy about the political nature of the song, which he felt was at odds with the Beatles’ style.
