Adding to the song's ethereal qualities, the musical arrangement includes a Lowrey organ part heavily treated with studio effects, and a drone provided by an Indian tambura. The song has been recognised as a key work in the psychedelic genre. Among its many cover versions, a 1974 recording by Elton John – with a guest appearance by Lennon – was a number 1 hit in the US and Canada. Cott, Jonathan (23 November 1968).
