 In 1991, former Guns N' Roses drummer Steve Adler, who was at Ribfest this year, filed a lawsuit against the band claiming they forced him to use heroin. Of course they did. Then booted him out of the band as he tried to kick his habit. Okay. The suit was settled out of court. Adler performed with Guns N' Roses in 2016 in Cincinnati. It was his first appearance with them since being kicked out of the band. Like you said, he's branched off.
