Demand the right for Shanda Andrew to sing

I am a member of the moose Lodge in some aunton va.bour bartender there is a professional singer yowerever when we have hands come in to play and they request that she assist them with a song our board members will not allow her to sing. She works between six and nine hrs a day with no break and as members we feel she should be allowed three minutes to sing a song because we want to hear her
