“A study of Clem Burke, the drummer in Blondie, found that drumming for 90 minutes saw his heart rate rise to the level reached by the average top-flight footballer, and for the same period of time. Burke’s body was put under such stress during his gig that his heart averaged between 140 and 150 beats per minute, even reaching as high as 190. He also burned up to 600 calories per hour during the scientists’ trials.”
