I left that band with the joy of escape, feeling I'd paroled myself from the singer's management-by-tantrum, feeling it was taking precious time away from writing, from my true love, from the things that mattered.
Five years later they were on a major label; today they're marketed as "The legendary XYZ".
Regrets? I suppose. It would have been a nightmare, but my songs would be known, and I would have automatic entrée to music circles closed to me today.
But, not really. The nightmare would have poisoned the experience, left me bitter and angry.
