Years ago I worked in the sound and staging industry. One of the first shows I worked was Van Morrison at Massey Hall. Just before the show started I was placed side stage and told if anything went wrong with the stage gear the company I was working for provided I was to fix it. I spent the entire show praying that nothing would go wrong as I had no clue what to do if it did. Over the next 5 years I worked many shows at Massey Hall but the first one is the one I remember most.
