Country legend Glen Campbell has passed away at the age of 81. Campbell announced he had been diagnosed with Alzheimers in 2011. He sold more than 45 million records over his career, topped the country singles chart 12 times, earned five Grammys and many CMA and ACM awards. He was inducted into the Country Music Hall of Fame in 2005 and received a Grammy Lifetime Achievement Award in 2012. He will always be the Rhinestone Cowboy. RIP Glen.
