I have two. The first was seeing Joan Baez in the 70s at the Myer Music Bowl in Melbourne, Australia and getting so sunburnt, I was almost hospitalised but the concert was worth it. The second happened to me. I was in England in 1979 with the Cobbers and the Dubliners invited us up to their concert at a working men's club about 60 miles from London. We were all sitting in the dressing room before the show when Barney McKenna grabbed Christy and myself by the arm and dragged us outside. We thought he was going to show us something but he took us through a curtain and the roar of applause made us realise that we were on stage. After a fast retreat, we found out that Barney was almost blind without his glasses and too proud to wear them on stage and had grabbed on to the wrong people. It was quickly sorted out and the real Dubliners went on stage and brought the house down.
