There was one awkward moment backstage at the Grammy Awards. But other than that, this Darius Rucker video interview is perfect. The awkward came right in the beginning when Rucker was asked to recall when he wrote “Wagon Wheel,” the recording that won him a Grammy for best solo country performance.The problem? Rucker didn’t write it. The song is, in fact, almost older than Rucker himself. It was originally written in the early ’70s by Bob Dylan and then later polished up by Ketch Secor of Old Crow Medicine Show. But whatever its origins, Sunday’s (Jan. 26) win his first Grammy since his band Hootie & the Blowfish won the best new artist award in 1996.
