Peter, I don't believe that Sear was on the album, and Roger was certainly given credit.
Thanks, folks, for soliciting my stories, but now's not a good time- I'm doing laundry (is this subject allowed on a music thread?) and packing to go to the doings in Frankfort, KY this weekend (see thread "Play Dulcimer With Me)!
I'll just tell a little bit- George did all the recording for the Folk City album with our Magnacorder and one microphone, which he moved selectively from mouth to instrument to another mouth, etc., throughout each number. When the reviews came out, most of them praised the "advanced modern technology" which enabled the production of such a crisp, clear yet mellow sound.
