Interesting question Greg
I think the "which steeleye" question is much harder to answer than the which fairport. I think after the sad loss of Sandy, there evolved a "generic" Fairport sound...which is a good one.
Carthy Steeleye is very different from Kirkpatrick Seeleye is very different from....and they're all good ones.
I do believe Bob Johnson to be one of the most underrated guitarists in this field though
Donning false beard disguise and ducking behind parapet....
