Fats opened for the KT in Vegas a few times. He passed away in 2007. He was one of a genre of guitar-playing singers who used a lot of humor (mostly jokes you've heard a zillion times before) in his show. He'd sing a bit and then interject some silly comment or joke and then go right back into the song as the audience guffawed. He was energetic and got the audience clapping and laughing. The perfect opening act.
