A long-haired mystery man in platform boots is at the centre of a new appeal more than 45 years after his death.
A man's body was found beside the A508, which links Milton Keynes and Market Harborough, having been struck by a car in the evening of July 9, 1975. His identity has never been known.
Now, volunteer researchers working with the Locate International agency think the man may have been called 'James Brennan'. They believe he was hitch-hiking home to Middleton, in Rochdale, from the Knebworth Festival in Hertfordshire, where Pink Floyd were on a bill that also featured Captain Beefheart, Linda Lewis and the Monty Python team.
