My wife and I saw Reba in concert about 14 years ago.
Three days prior to the show, Reba had broken her leg in a skiing accident and had a cast that went clear up to her hip.
Lots of musicians would have, understandably, canceled the show...but not Reba.
This concert was "in the round" with a stage in the middle of the floor and the crowd on all sides. So what they did was, they put her on a rotating bar stool and the stool had wheels on it. They had a line atached to it and they would pull her back and forth across that stage from one end to the other, while she spun around and sang to the crowd with her broken leg sticking straight out onto a foot rest they had rigged up. Her dancers did their choreographed moves all around her, while she "danced" with her upper body and sat on that stool for about 2 hours.
It was a great concert and I was impressed with the respect she showed for her fans by going out there and singing her ass off and putting on a good show with a broken leg.
