Yes this happens at a few clubs that I used to attend. One bloke has been singing the same 3 or 4 songs every week for about 25 years. I wouldn't mind but, Leaving On A Jet Plane, Streets Of London, Ride On, Colours etc can get on your nerves week in week out. Then there's the club where somebody has, for the last 10 years, every week sung/spoke this awful song about a "moggy" getting run down and the regulars still laugh at the punch lines as if they had never heard it before! It's more interesting to sit and watch telly at home. These same clubs wonder why they are loosing audiences.
