Hot dog - we have a wiener!
Tim Turner's Narration always stuck in my head as one of those wonderfully pretentious 60s band names, and after I bought the "Look at Life : Swingin' London" DVD a few months ago, I had my "Ah! So *that's* where Ashley got it from!" moment...
IMDb suggests that Tim Turner may still be with us (he'll be 82 if he is)... you could make a fantastic little intro film for FC's Cropredy set next year in the style of the Look at Life series and get Tim to narrate it...
. . .which for me, and I would guess millions of others, still doesn't answer the question what is the link to Fairport? Tim Turner? At a loss, sorry.
