British rocker Yes have canceled their 40th anniversary tour of North America after singer Jon Anderson was diagnosed with acute respiratory failure.

The 63-year-old was hospitalized last month after a severe asthma attack, and doctors have told him he will jeopardize his health unless he rests for at least six months. Anderson says, "I'd like everyone know how deeply disappointed I am by this turn of events. I was looking forward to celebrating our music with the amazing family of Yes fans once again; but as we all know, health must come before anything else."

The tour, the band's first trek through North America since 2004, was scheduled to begin on July 12th in Quebec City, Canada.
