The Old Crow Medicine Show was in town tonight.   A lot of good songs and interesting and moving arrangements and one of the most enjoyable concerts I have seen in a long while. Ralph Stanley was in town last weekend and I left early.   I enjoyed Ralph but the rest of the band was pretty much run of the mill bluegrass.   Old Crow was top notch from start to finish.   The final encore was a rendition of Dylan's Joey.   The audience had a few wrinkled faces but many more of the younger generation but all seemed to appreciate this original band.
