How many Billy Bob Thornton films can you name, off the top of your head? You might reel off Sling Blade, Bad Santa, Armageddon, Pushing Tin, Monster’s Ball, A Simple Plan.

Now, how many Billy Bob Thornton albums can you name, whether as a solo artist or as a member of his country-pop band The Boxmasters?

Not so easy, right? Nevertheless, as his breathtakingly petulant recent performance on Canada’s CBC Radio One illustrates, when Billy Bob Thornton is promoting his little-heard of band he’d rather you pretend you’ve never seen any of his blockbuster movies. Even the Oscar-nominated ones where he bangs Halle Berry or plays a mumbling, mentally-deficient, murdering mentalist.
