Radiohead have paid tribute to their drum technician after he was killed in a tragic accident just hours before the band were due to go on stage.

The 'No Surprises' stars were setting up for a performance at Downsview Park in Toronto on June 16 when the event's entire stage roof collapsed, killing their 33-year-old crew member Scott Johnson.

The group posted a public message to their official website and their drummer, Philip Selway, wrote:

"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."

The concert was immediately cancelled following the disaster and you can watch footage taken from a helicopter of the scene below:
