greetings!
Check out Fred Small - long time U.U. and folk writer/singer. He recently became a miniter too. His music is in "Rise Up Singing" and other places. Charlie King does the U.U. folk music circuit as well. Plus there is a host of others. At home (I'm at work) I have a list of "Alternate UU Musicians" (the alternate meaning those generally not doing hymms and/or Classical music.) I'll try to remember to send myself a copy of the list and post it to the thread.
Pax.
