I visited the American Museum first with Shirley Collins to help her present her show, "America Over The Water". We didn't have a lot of time that day as we had a lot of travelling to the next day's gig, but I vowed I would return... and I did the next time that I was in that area and I enjoyed it thoroughly.
In fairness to the shop and to the musical presentations programme, the staff have no folk music background, but I found them to be very open to suggestions, though it was explained to me that their resources are quite limited. I believe they took up my suggestion that they book Bayou Seco and I know that they consult Kate Lissauer about presentations.
