Jerry Lee Lewis gives a rare live performance for his new album 'Last Man Standing' at Virgin Megastore. Hollywood, USA - 12.10.06

The GREAT BALLS OF FIRE hitmaker turned his back on rock `n' roll to become a country maverick in the 1960s and believes the likes of KENNY CHESNEY, FAITH HILL and KEITH URBAN could all learn a lot by going back to their roots.

Speaking to men's magazine Blender, he says, "It's crap... It all sounds alike to me. They're not doing any down the-road country music.

"I don't know what they're doing - I don't think they know what they're doin', either. I think it stopped being good when I left there (Nashville)."
