We have an old film that my man George Pickow did, of Merle and Mose Reager talking and picking/singing together...I remember they had a sort of confusing conversation concerning "the thumb-lick with the thumb-pick," or "without the thumb-pick," and after the film was made, Merle told us they had after all come to the wrong conclusion! But it's down now on the film for all time... on the film, Merle plays and sings, "I Am a Pilgrim." This was in the early sixties. Also on the film are Clarence Ashley and his band including Doc Watson, and The Walker Family from Nobob,KY (residents have now changed the name of their p.o. to Summer Shade, KY. Some ladies' club was probably responsible. The name of the film was, "Hillbilly Music", part of a series called, "Lyrics and Legends." We still have a copy.
