The 'whooping and shrieking' phenomenon began in the earlier series of 'talent' shows like X Factor and Britain's Got Talent, and now it's taken over everything where any modicum of appreciation is being called for.
It's seriously tiresome, but we have to live with it, hard though that is.
I was watching Steve Harley play at an outdoor festival, and I was a couple of rows from the front with a really exciteable woman behind me.
At each of the two silent pauses in 'Make Me Smile (Come Up And See Me), she let out this foghorn 'Whooo!!!' and Harley just looked at her in disgust.
I wanted to turn round and ask her - "Do you really think his performance is enhanced by you butting in with that stupid noise?" but what would be the point? She wouldn't have understood, but been hostile anyway, so I seethed internally - again.
I know I'm getting old, but I don't embellish liver performances with my unscripted additions, it's bad manners.
