I went to a concert in a village hall yesterday evening to see the Mellstock Band. There was a group of about 10 of us who regularly go to folk events sitting together and we were joining in at appropriate times but the rest of the audience did not join in. After a while, the lady sitting next to me said "Please would you NOT sing". I said "I'm very sorry". She said "I paid to listen to the band not to listen to YOU sing". I felt rather upset because I had only been singing quietly, not with gusto as I would at Whittlebury. I kept quiet during the rest of the concert. Was that the right thing to do or should I have continued singing regardless?
