On Eric Clapton's new album I Still Do, the bluesy track "Somebody's Knockin'" is a cover of an unreleased song by J.J. Cale, Clapton told Billboard. The recording originated when Clapton was working on his last LP, the 2014 Cale-appreciation album The Breeze.
"When I did this J.J. album called The Breeze, which was a tribute to J.J. Cale, when I met up with his wife, Christine, I said, 'Is there anything lying about that I could maybe finish or work with?' She gave me two CDs of unreleased material which is all fantastic. We covered 'Somebody's Knockin','" Clapton said.
