Written while under the influence of LSD, It's All Too Much was the second song by George Harrison to feature on the Yellow Submarine soundtrack (1969).
Based on a droning G chord, the song transposed the continuing influence of Indian music onto a psychedelic setting. The lyrics combined the cosmic philosophy favoured by Harrison with some nursery rhyme-style whimsy.
It was the longest Beatles track (6'28'') when it was recorded in 1967 (during the Sgt. Pepper's sessions) before Hey Jude in 1968.
