It is BBC anchorwoman Jackie Bird’s most famous interview and, even today, she finds the story of the man who almost got away with living his life over again utterly compelling.
Brian Mackinnon was 32 when he returned to his old high school and fooled classmates and teachers into thinking he was a Canadian teenager called Brandon Lee to fulfil his dream of going to university and becoming a doctor.
A quarter of a century later, the story is being told in the film My Old School written by a former classmate and starring Alan Cumming but whose voice is actually that of Mackinnon himself.
