So, it’s not all that surprising to learn that quite a few tunes from the genre were not allowed on radio stations at one time or another,” (Yahoo) ” … Far Out ranked The Beatles’ 1967 song, ‘Lucy in the Sky With Diamonds,’ as the best classic rock song ‘banned from radio.’ According to the publication, the John Lennon-penned hit, off the acclaimed record, Sgt. Pepper’s Lonely Hearts Club Band was deemed not radio-friendly because of its initials. The official Beatles website reported that ‘Lucy in the Sky With Diamonds’ was prohibited by the BBC due to theories that it was inspired by LSD. Far Out reported that Lennon stated the rumors were untrue.”
“… the Faberge psychedelic egg that was finally laid on the eve of the Summer of Love came so fully-realised that it changed the way we listened to recorded sound forever,” (BBC). “Sgt Pepper’s is at once warm and familiar, yet wild and strange … Yet what was revolutionary was the sonic carpet that enveloped the ears and sent the listener spinning into other realms.”
After the tune starts in A major, there’s a shift to Bb major for the pre-chorus at 0:32. At the 0:50 mark, the G major chorus begins, built around a repeated I-IV-V chord progression. At 1:08, the pattern repeats.
