Hank Williams' handwritten notebooks and two guitars belonging to Hank Williams Jr. have been added to the Country Music Hall of Fame and Museum's exhibit, Family Tradition: The Williams Family Legacy. The notebooks are filled with Williams' writings, including lyrics to many never-recorded songs and notes he made while researching Cajun cuisine for his hit, "Jambalaya." Original handwritten lyrics to his unpublished song, "I Thank My God for You," are also now on display. The lyrics are written on stationery from New York's King Edward Hotel where he stayed during a 1951 appearance on the Perry Como Show. In addition, Hank Williams Jr. has loaned a Martin D-18 guitar to the exhibit. Williams describes the instrument as his "therapy guitar" because he played it in 1975 while recovering from a fall down Ajax Mountain in Montana. The exhibit runs through Dec. 31, 2011.
