I did not want to get involved with any discussions Since I was told to bugger off By someone who did not agree with me. However Joe Offer hit it right on the head.At a certain age it becomes difficult if not impossible to memorize fresh material. I am 71 and have been singing for almost 50 years Yes I need the words in front of me if I am to sing any new material other wise it would be the same songs that I learned 30 or more years ago. My MD calls it the aging process and it happens to us all, There is no way to get around it. It is something we can ALL look foreward to if we like it or not. So sing on and enjoy it.
