..Heres the final answer.
Andy Ellison, on vocals, ended up in a band signed to Chiswick called the Radio Stars. They made TOTP in 1978 with "Nervous Wreck", and the big push came later with a cracker of a pop song called " From A Rabbit".
I met him twice as a kid, at his gigs, and had no idea he was from Johns Children.
I have no idea what he is doing now, also.
The "B" side of "Nervous Wreck", is written by Marc Bolan, and is called "Horrible Breath (you scare me to death)".
Anyone at our gigs in Nottingham over the next three days please say hi!, and more quizzie stuff please!
I don`t think you googled JK, as I know the stories, but I do believe Andy is shorter than Marc was, and so it would appear the band may have been put together.
Nobody likes a band of differing hights.
Peter Crouch on bass???Nah..
Good trivia though innit?
