John liked the song itself and he participated in the recording of Elton John’s 1975 cover version (under the pseudonym Dr. Winston O’Boogie).
However, John was disappointed in the Beatles arrangement of the 1967 recording, saying that not enough time had been spent recording the song.
He also thought that he had not sung it very well, although many listeners would disagree.
Finally, John was peeved over the speculation that he had intentionally titled the song so that the first letters of each word spelled out LSD.
John insisted that that the song was inspired by a nursery school drawing by his 3-year-old son, Julian. Ringo has confirmed this story, saying that he was present when Julian came home from school with his drawing of “Lucy in the Sky with Diamonds.”
The surreal imagery in the song comes from one of John’s key influences—Lewis Carroll and his “Alice In Wonderland” books. Paul came up with the phrases “newspaper taxis” and “cellophane flowers.”
John’s love of the Goon Show inspired the phrases “plasticine porters with looking glass ties” and “kaleidoscope eyes.”
The song was banned from airplay by the BBC because of the LSD acronym.
