Several minutes after Daltrey's departure, guitarist Pete Townshend announced that Tuesday night's show had been canceled. 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 rescheduled for March 25.
