We went to see Seeger and he ran me off. I was little, 5 or 6. He was rude. Woody and Arlo, for my money, are both quite a bit more touchy-feely, happy-happy and not so dark as Baez. I like Collins but I prefer Joni Mitchell. And there's always PP and M and I would argue they did as much as anyone for folk music.
I agree with you on Joni when it comes to songwriting.She's a songwriting genius,IMO.I've never been a big fan of her performances,however.Agree with you on PP&M also.Some of the film clips from Newport that I've seen recently strengthened my admiration of their talent as well as their stage presence.
