Sometimes I think I'd like to form a band - then I read something like this and reassure myself I'm better off solo. If you are lucky enough to find like-minded and committed colleagues though I'm sure it's well worth the effort. 3 individuals didn't make a team in your case; you are right to split. The language you use "a bloke on melodeon, a gal that sings and plays the whistle" says everything about how you feel Ted.

Good luck with future music ventures.
