The Bok, Muir, Trickett recording is on a Folk-Legacy cassette titled A Water Over Stone, which I don't believe is available on CD. Rounder/Philo hasn't released the Jean Redpath & Lisa Newstadt with the Angel Band recordings on CD, either.
And I can't bring myself to spend money on cassettes, even if Riggy's singing on them. Heck, I can hear Riggy singing live and in person.
Darn.

I mean "darn" about the cassettes - it's a privilege to know Riggy and to hear him sing.
