Taylor Swift isn't the only country superstar inviting unlikely duet partners onstage during their live shows. Over the weekend, actor Jack Black joined Keith Urban for an animated cover of Charlie Daniels' 1971 chart-topping country classic, 'The Devil Went Down to Georgia,' during the Aussie singer's show at Los Angeles' Staples Center. (Watch a fan's video of their duet below.)

Last week, Keith was joined by actor Russell Crowe during the singer's Vancouver concert stop, collaborating on the Johnny Cash standard, 'Folsom Prison Blues.' "We don't usually do this, but a friend of mine happens to be in town shooting a movie so he's here tonight," Keith told the crowd before his fellow Aussie appeared on stage with an acoustic guitar in hand.

Keith is nearing the end of his Get Closer world tour, with remaining dates in Denver, Colo., Milwaukee, Wis., Chicago, Ill. and Minneapolis, Minn. The 'Long Hot Summer' singer is also scheduled for three Grand Ole Opry appearances before the end of the year. Click here for dates and ticket information.

As for Jack, he certainly dressed the part, but does the 'School of Rock' actor have chops to be a legit country singer? Watch below to judge for yourself.
