'Waiting on a Friend' was the second single off the Rolling Stones' album 'Tattoo You'. Unlike 'Satisfied Mind', there is a once and forever definitive version of this one: the Stones version.
'Tattoo You' was mostly a bunch of old unfinished demos rewritten and retooled; 'Waiting on a Friend' in particular was a promising track Mick Jagger had never got around to writing lyrics for. The loose, lighthearted lyric Jagger eventually came up with -- and the Sonny Rollins saxophone that sends the song in the stratosphere -- make the album version a testament to keeping old ideas kicking around, and to keeping old friends close. The Stonewall version is a testament to alternate tunings, snippeting soul standards, and also to friends, too.
