Billy Bob Thornton pretended to have amnesia and forget his own band during an interview.
The actor-turned-musician became difficult after a Canadian radio host mentioned his Hollywood career yesterday (08.04.09).
Billy Bob was due to be interviewed and perform with his band The Boxmasters, but became upset when he was introduced as an "Oscar-winning screenwriter, actor and director".
When CBC radio DJ Jian Ghomeshi asked him how he formed the band, Billy Bob replied: "I don't know what you're talking about. I'm not sure what that means."
He then proceeded to give monosyllabic or short answers to questions, or spoke about something totally unrelated.
The 53-year-old star pretended not to have met his touring partner Willie Nelson and also compared Canadian audiences to "mashed potatoes with no gravy".
Billy Bob - who was previously married to Angelina Jolie - announced he wouldn't sing with the group and would only play drums - despite the fact there were no drums in the studio.
Billy Bob said: "We don't cart those around at six o'clock in the morning."
The band then had to perform without a vocalist.
Ghomeshi said after the show: "To not answer questions because I made the apparently egregious mistake of calling him an actor as well as a musician, it just seemed a little absurd."
