Running to 5 minutes 23 seconds, "Rat Bat Blue" is the fifth track - Side 2, Track 1 - on Who Do We Think We Are
. A group composition, it is said to be Roger Glover's favorite track on the January 1973 album and is, as he told Michael Heatley in The Complete Deep Purple
, "about picking up a loose chick for the night."
Two years later, Glover married his first wife, so presumably he had outgrown the rock star/groupie phase by that time.
