Eduardo recommeneded a comp (thanks) and I've heard rumours of Nesmith's solo stuff, but I read in the Bert Jansch biog that in the seventies he was a rampant born again Jesus freak human coke hoover, so that sort of dampened my urge to follow that particular trail ( careful K Trout!).
He he, i heed your warning, although David Crosby was similarly powder-centric and managed to produce one of my all-time favourites, 'If I Could Only Remember My Name'. Oh, and John Cale of course. They may be the exceptions to the rule, mind.
