You must have heard plenty of heckles over your years of gig, comedy etc going. Maybe not great but I was told off by the act in question for silent heckling. Waiting for Roy Harper, sat at the front on the floor I decided the support act wasn’t for me so turning my back and using the stage lights I proceeded to carry on reading my book. Some time later I realised I was being berated from onstage by the act. Other people hadn’t enjoyed his act but I got it in the neck for reading whilst he was playing. You must have heard plenty, why not share ’em and any snappy comebacks.
