Chuck Berry collapses on stage in Chicago Jan 1st 2011
The 84-year-old Berry’s head lay on a keyboard, and he didn’t move for a couple of minutes before he was helped off stage by three people shortly before 10:30 p.m. He returned 20 minutes later after most of the auditorium had cleared out. He tuned up his guitar and tried to play before telling the audience he had no strength. He then did a variation of his legendary duck walk off stage. (from Chicago Sun-Times)
