When I was younger, so much younger than today, they were everywhere. You couldn't switch on the telly without seeing one. Roy Castle, Lionel Blair, Bonny Langford etc. Everywhere. No light entertainment show was complete without tappy-tappy-tappy-tappy at some point. And Brucie would do his bit. And The Roly-Polys.
It's all ballroom now. What happened to them all?
