Weight, Time Constraints May Have Contributed to Radiohead Stage Collapse

The Ontario Ministry of Labour, the Canadian government department that develops and enforces workplace health and safety standards, is looking at the roles of at least four companies involved in the staging and staffing of Saturday's stage collapse in Toronto that killed Radiohead's drum tech Scott Johnson, 33.

The accident, which occurred at Downsview Park just an hour before gates were to open to the public for the sold-out concert for 40,000 people, is currently under investigation. The Ministry's spokesperson Matt Blajer told the Toronto Star that it has asked Toronto's Optex Staging and Services, Inc; Toronto's Nasco Staffing Solutions; promoter Live Nation Entertainment and Radiohead's Ticker Tape Touring to comply.

Information on companycheck.co.uk lists London-based Ticker Tape Touring LLP as a limited liability company with "Current Directors" Colin Charles Greenwood, Thomas Edward Yorke, Philip James Selway, Jonathan Richard Guy Greenwood, Edward John O'Brien -- all members of Radiohead -- along with a company called Random Rubbish Limited.

"While Blajer could not disclose specifics, he said the ministry has issued orders 'mainly to Live Nation,'" the newspaper reported. "Stage blueprints signed and approved by a professional engineer have already been provided to investigators."

Because of the scope of the show, which was to take place on the park grounds that is not a permanent concert venue, investigators are trying to find out if other companies were involved in the staging and audiovisual production.

Blajer told the Star, "We're still trying to figure out who owns what, who's responsible for what. You've got lighting technicians, sound technicians, the band's people -- we're trying to figure out who worked for whom."

Optex, Nasco and Live Nation had not granted requests for comment at press time.

Downsview Park was the site of the 2003 "SARS" concert, headlined by The Rolling Stones, which drew close to a half-million people, the biggest in Canadian concert history.

The Foster The People concert tonight (June 19) is "proceeding as scheduled," reads a notice posted on the park's homepage. Other concerts at the grounds this summer are Edgefest July 14 featuring Billy Talent, Death From Above 1979, Young The Giant, The Sheepdogs, and more; and Heavy T.O. July 11 to 12 with System of a Down, Slipnot, Marilyn Manson and others.
