Ever wonder who taught John Lennon how to play harmonica? That's right, it was Texan blues rock bad boy Delbert McClinton. In the 1960s McClinton found chart success with the hit "If You Really Want Me To, I'll Go" while singing for the Rondells. He joined up with Glen Clark in the 1970s and then had a career as a solo artist and popular session musician, playing with folks like Bonnie Raitt and Tracy Nelson. As a testament to how talented he is, McClinton's songs have been covered by the likes of Emmylou Harris and Waylon Jennings. He still continues to play stellar blues rock, often traveling knee-deep into Americana territories and wandering into the sonic canyons of Lone Star State-styled country rock.
