Billy Bob Thornton and The Boxmasters have scrapped the remainder of their North American dates as Willie Nelson’s tour opening act after fans booed them onstage at a show in Toronto on Thursday night.

The Oscar winner upset Canadian fans during his controversial radio interview on CBC radio last week. He became upset when jock Jian Ghomeshi mentioned his acting career during the show’s opening introductions. Billy insisted his “mashed potatoes with no gravy” comment was not anti-Canadian, adding, “Boo all you want, but I want to say something – we’re really happy to be here.”

Following the disastrous gig, Billy Bob and his country-pop band, The Boxmasters, pulled the plug on the rest of their tour.

“At this time, no reasons have been announced but the remainder of the tour will continue as scheduled without The Boxmasters,” according to a post on Willie Nelson’s official website on Friday.
