I was performing at an Earth Day event in Toronto recently. There was a lovely poster for the show, which read, "Earth Day Show by David Archibald." So far, so good. The interesting part was the colour photo beneath the type. It was a David Archibald alright, but not me. It seems there is a well-known Climate Change expert of the same name. I'm sure he is a learned fellow and does great work, but I have to say we don't look like we're related. If anyone came to the performance expecting an academic lecture on global warming, they would have been surprised to see me tearing around singing on roller blades.
