Glen Campbell has died at the age of 81 after a long and courageous battle with Alzheimer’s disease. A self-taught prodigy, he rose from a poor rural childhood to release over 70 albums and sell 45 million records. Campbell had a distinctive  country pop sound on hits like Gentle On My Mind, By the Time I Get to Phoenix and Wichita Lineman. In 1968 he recorded a duets album with Bobbie, and their easy camaraderie and obvious chemistry made the partnership a great success, resulting in a gold album, and several hit singles including Let It Be Me and All I Have To Do Is Dream. He carried on making music, releasing acclaimed new albums with younger musicians until his health gave out. In 2005 he was inducted into the Country Music Hall of Fame.
