The Who’s 50th anniversary tour rolled through Nassau Coliseum on Wednesday night and, according to a report from Newsday, lead singer Roger Daltrey threatened to walk off stage due to marijuana smoke near the stage.

Daltrey has a well-known allergy to marijuana smoke that affects his singing voice and it began to take its toll almost immediately as the opening “I Can’t Explain.” The singer said, “my voice is shutting down” and told the smoking audience member that “the show will be over” if it didn’t stop. That led to some banter from Pete Townshend and Daltrey, as the guitarist tells him to “stick it up his fucking ass.” Watch below.

Daltrey recovered and was able to finish the show, with his voice reportedly getting stronger as it went along.
