There are 4 tunes: Laura, Sukey Jump, Windjammer, and John Hardy. He was a great player, too bad he didn't record more tunes on the accordion. Played a one row diatonice with 3 stops. You can find the picture in "Leadbelly and His Windjammer" in American Music Volume 12, Summer 1994. pages 148-166.
