@layman,
These recent posts reminded me that Keith Richards and Jerry Lee have something in common: They were both punched out by Chuck Berry.
Chuck was convicted of armed robbery when he was 18 or 19, and was a boxer in prison, so it was best not to piss him off.
According to Jerry Lee, the confrontation was over who was the king of rock and roll. According to Jerry Lee, it was himself. According to Chuck, it was, naturally, Chuck. Jerry Lee said that, after it came to blows: "I didn't argue with him no more."
In Richards' case, when they were playing a gig together, Keith started playing some licks on Chuck's guitar, while Chuck was gone. Chuck came in, saw him with the guitar, and decked him, saying, "nobody messes with my guitar."
Keith's comment was: "It was Chuck's greatest hit, ever."
