Rockers Radiohead have paid tribute to the tragic crew member who died after a stage collapsed ahead of their show on Saturday night.

The British band was scheduled to play at Downsview Park in Toronto, Canada but the venue's structure collapsed in the afternoon, killing drum technician Scott Johnson.

The devastated group cancelled the concert, and drummer Philip Selway posted their condolences on their official website, writing, "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."

Three other people were injured by the structural collapse - a man was hospitalised with a head injury and two others were treated at the scene.

Johnson, 33, had toured with other bands including Keane, Portishead and The Charlatans. (MH/RS/CL)
