You could look upon it as a suspension. There was an older tradition of band leaders to dock pay and suspend members for bad behaviour, Mayall might've been on that kind of a trip. Jack Bruce seemed to always be getting the sack from somebody or other. Peter actually came back once too after leaving for some recording date, that produced the B-side 'Jenny'. Jenny Boyd?
Aynsley was out and then came back after Mick Fleetwood's stint, then out again. Even Pete Frame would have trouble mapping it all out I'm sure.
