Jed, I would modify your statement - commitment to individuals who are themselves committed to the band, yes, I agree it comes first. But those who are not committed to the band effectively write themselves off, and deserve no loyalty.

The lady in question was not committed to the band, not putting in the effort required. Her place in the band was therefore forfeit.

There remains the responsibility of the bandleader to warn such uncommitted members, give them a chance and eventually let them go. This is where Ted fell foul, because he did not go through those steps and let the lady find out de facto that she was no longer a member.
