MC's Perogative is the rule at Maidenhead - There are usually FAR too many singers on Guest nights so it is down to whoever is running the evening to get a good balance of singers - Often the regulars dont get on if there are too many new singers , or old friends we havent seen for a while .
On Singers/Musician nights , its All Comers , and then we often dont get twice round , though rarely do we NOT get everyone on who DOES want to perform .
