Written by Mick Jagger and Keith Richards, "Worried About You" is slow ballad first produced for 1976's Black and Blue.
This is most evident with the song's guitar solo contributed by Wayne Perkins, an early contender for the lead guitarist spot left open after the departure of Mick Taylor.
Like some songs for Black and Blue, "Worried About You" was recorded in Rotterdam, Netherlands, using the Rolling Stones Mobile Studio.
With Mick Jagger on electric piano and lead vocals (using a falsetto voice like the ones he employs in the earlier released, later recorded songs "Fool to Cry" and "Emotional Rescue") with Richards providing prominent harmony vocals during the chorus, Perkins and Richards perform guitars.
It is notable for showing Ronnie Wood, the eventual choice for the Stones' lead guitarist, performing Perkins' solo (similar to the videos for "Waiting on a Friend" and "Hot Stuff", which were actually played by Mick Taylor and Harvey Mandel respectively).
