Well, I think in 90 minutes there's no way I can cover everything. I wouldn't do a good job of blues singing, so I'm gonna have to stick to folk. Blues would be an entirely different category and would warrant a separate evening - done by somebody else, not me. You know I'd forgotten Burl Ives - (duh!).   I like his singing but not his politics - didn't he snitch on some people and get them blacklisted? And then there's the whole calypso thing.... As to doing th whole decade, well I'd like to scatter in song from the gamut of the sixties, although the late sixties was very different from the early sixties, and of course the "Folk Revival" spanned from the fifties to the seventies...see why I'm overwhelmed????
