He could not read music, but if he heard a tune a few times, he could play it. When he was younger, cursing the day of his audition and he d

Songs such as the Tennessee Waltz, Harbor Lights and around Christmas time, the well-known rendition of

We learned the words to the hymn when we were very young, and would sing it with Dad when he would play and sing. Another song that was often

Davey, Davey Crockett, King of the Wild Frontier was a favorite song for the family. He knew we enjoyed the song and the program and would often get out the mandolin after the program was over. I could never get over how he could play the songs so well after only hearing them a few times. I loved to sing, but I never learned how to play河入海流。欲穷千里目，更上一层楼。译专心-专注-专业
