The concert was cancelled as soon as the death became known. It was to have been the final date on an 11-show tour of North America for Radiohead.
The accident also injured three others, one seriously. The 45-year old man was taken to nearby Sunnybrook hospital with non-life threatening injuries. The two other men received minor injuries.
40,000 fans would have attended the outdoor concert.
Radiohead posted the following statement at their website:
“We have all been shattered by the loss of Scott Johnson, our friend and colleague. He was a lovely man, always positive, supportive and funny; a highly skilled and valued member of our great road crew. We will miss him very much. Our thoughts and love are with Scott’s family and all those close to him.”
