Jane - Great that Geoff and hopefully you will be there. I think there's a good chance that Diane Jones'll be there as well - she's Dwight Diller's replacement banjo teacher at the Gainsborough workshops. She plays with the Reed Island Rounders with Betty Vornbrock and Billy Cornette, and I know she enjoys sessions much more than Dwight ever did - Dwight could never stand to see people thrashing about and misusing technique, which is half the fun of sessions. See my post after Oombanjo's in this thread for my recommendations on old time women singers. Carl Jones and Beverly Smith are great too, as is Guy's Lily May Ledford.
Cheers
