Don't get me started on that mentality, I had one of my middle-aged singers almost attacked and certainly verbally assaulted for having the the temerity to sing 'Needles And Pins' by the Searchers!!
He was accused of being a "white, middle-aged, sexist misogynist", by some 19-24ish female, (I won't use the term lady, she certainly was not one with what came out of her mouth!). Luckily the singer was supported not only by myself but also by the venue owner who 'politely' informed her her custom was no longer welcomed in the venue. (In fact i think she told her to go outside with all the other snowflakes before she had a meltdown.... It wasn't even winter!)
