Wyowoman, Stairway to Heaven as a bluegrass number would be wonderful. (You don't find too many bluegrass musicians in the section of Steve's Music where the sign banning it is posted. :-))
If you like that version you would probably enjoy some of the 'mixes' that Toronto band Jughead plays. The one that pops to mind is "Born to be Special" where they weave together "Born to be Wild" and "Orange Blossom Special". It's a real crowd pleaser. (So was the flaming washboard during "Like My Fire" at their 10th anniversary party last Thursday.)
Mary, re: Barretts, How Can I Keep and Today While the Blossoms. You and I would not meet during bathroom breaks. :-)
