Years ago I played in a uke group. We had no sheet music, but all had a good ear for music so we got our songs off records (Yes, I'm that old.) We had fun with the folk music that was popular at the time. Often, I had a whole different set of words to the songs we played and sang. In fact, we actually wrote a few new verses to some of them. At the time I did not know I had an issue with hearing loss. They just thought I was poetically creative. 🙂 I had no trouble with the tunes, just the words.
