Dear M, you DO have a great upper register. Ghost of William-O has a great eerie sound. a cappella, with lots of ornamentation."Straw into Gold" has a lot of great stuff on their 3 tapes, sung in harmony, but it doesn't have to be.
(I just drove home from Portland sing along to "All that is gold do-es not glitter/All who wander are not lost...)
