Very good quality [recording] Graham and a historical artifact, thanks! It's also a reminder that Britain in 1968 s was still very conservative and not all Flower Power. I didn't like talent shows than [or now] or bland performers but the contemporary colour You Tube footage of Judith Durham with The Seekers, live in Australia, around the same time, changed my mind about them. You're right, there is a direct line from Hughie Greene down to Simon Cowell, in more ways than one
There's a much sadder one to the present day as well in Greene's personal life.
