There appears to be a Scot (originally from Irvine, just down the road from Glasgow) called Alex Wotherspoon living in Carlisle. Unfortunately his Facebook profile isn't available:
https://www.facebook.com/public/Alexander-Wotherspoon
Neither the BT Phone Book nor 192.com lists him but that might well mean that his phone number is ex-directory (as the majority of residential numbers now are) and that he's ticked the box to be excluded from the edited roll on his electoral registration form.
Draft letter:
"Dear Sir,
We are trying to contact an old friend, Alex Wotherspoon, who lived on Ardencraig Road, Glasgow over thirty years ago. We believe that he may now be living in the Carlisle area. If he (or anyone who knows him) would be kind enough to get in touch with us, we would be extremely grateful.
Yours in hope
Bert Smith and Graham Bloggs
(23 Railway Cuttings, East Cheam)"
