I once had an experience similar to the one noted by the teacher involved in all of this. I was singing at a restaurant - going from table to table. I sang "The Black Velvet band" for a pair of women. No reason. They hadn't made a request. One of them burst into tears. It had been her husband's favourite song. He'd been dead exactly a year. Her friend had taken her out so that she wouldn't be alone at home by herself that night. Leaving aside the strange coincidence ....it makes me wonder OOOOOH it makes me wonder...
Cheers, Joy
