I got to know Vaughn Horton in the early 1980's. We talked a lot about his music. Now this is what he told me. He said that Jimmie Rodgers was a frequent visitor when he would stop overnight at his father!s home in Pennsylvania. On one of those stopovers he gave him "Mocking Bird Hill"' which he, Jimmie Rodgers, said he would record. Jimmie was supposed to have record it on what turned out to be his last recording sessions in May, 1933. But Jimmie died before recording it. Folks made fun of his "tra la la twiddle de de" song for years. Then his group The Pinetoppers recorded, then of course, Les Paul & Mary Ford, followed by Patti Page. And the rest is history. Now I can only tell you what Vaughn told me.
