I saw Elton John & Billy Joel in their Piano Man (Men?) Tour. 7th row on the field at Busch Stadium. I've always liked both, but Elton John had - oh my god - the entire audience enthralled. He left the stage for a while and his drummer did it too. I can't begin to describe how they did it - but - damn - it's worthy of study.
