TAMPA, Fla. - Fans of the Who left a Tampa amphitheatre disappointed after lead singer Roger Daltrey walked off the stage during the band's first song.

Several minutes after Daltrey's departure, guitarist Pete Townshend announced that Tuesday night's show had been cancelled. He told the crowd that Daltrey had bronchitis.

"I just talked to Roger and he can barely speak," Townshend said. "I tried to get him to come out here, but he's really, really sick."

The 9,000 people at the show cheered when Townshend told them the concert would be made up March 25.
