I remember seeing him at MSG many years ago. He told a story about being impressed by one of his heroes who played two penny whistles at the same time. Watt then practised doing that for months until he too could play a tune using two whistles. Then one night in a folk club. his hero came up to him and said "that was great, how did you do it"? Watt replied "what do you mean, I first saw you doing it". "Aw no, I was only kidding" came the reply!
