Edit 4a for headphones, August 2023. Recorded December 4, 1965. Released in the US on the compilation album "Flowers", July 1967. I didn't find this song on ANY other album! Now combine that with the information that is in the next line and you will probably understand the reason why this song is only on "Flowers"... (or it's the serious bass distortion all over in this song).
This is a Brian Jones song, because on this song he played harpsichord, autoharp, marimba, congas, piano, electric guitars, sang backing vocals.
Keith Richards: electric guitars and backing vocals.
Lead & backing vocals: Mick Jagger.
Bass: Bill Wyman.
Drums: Charlie Watts.
