Thanks for all your suggestions. I can see resemblances with them all, and may have to go with them, but I'm not convinced. As a life-long Leeds fan Sarumite, I'm sure that no.12 is not Uncle Ken, but thanks for your input anyway.
Thanks eddiebun, I might just give it one more try as you suggest. Thanks also razza, I agree at first glance I thought he was Roger Whittaker too, but there is something not quite right about him.
