RUSSELL CROWE - PERFORMS WITH KEITH URBAN IN CONCERT
VANCOUVER, Canada. (AP) -- This is what Russell Crowe does on his off time from filming "Man of Steel." He lets his rock-star side come out, joining Keith Urban on stage at Urban's concert last week in Vancouver, Canada. With Crowe at the mic and both playing guitars -- and with backup from Urban's band -- they did a blazing version of Johnny Cash's "Folsom Prison Blues." Twice, Crowe jumped in the air as the song was ending, just like a real rock star.
