Gregg Allman passed away at age 69 on Saturday. The legendary Southern rock pioneer, who founded The Allman Brothers Band, died of complications due to liver cancer, his manager confirmed to Variety. Gregg "passed away peacefully at his home in Savannah, Georgia" and struggled with "many health issues over the past several years." He was diagnosed with hepatitis C in 1999 and underwent a liver transplant in 2010. Gregg composed such classics as "Midnight Rider," "Melissa," and "Whipping Post." Gregg is survived by wife Shannon and children Layla, Delilah, and Devon, as well as Elijah, whom he shares with ex-wife Cher.
