PAUL McCartney and his wife, Linda, emerge from Campbeltown Sheriff Court in March 1973, after a £100 fine had been imposed on him. He had pleaded guilty to knowingly cultivating five cannabis plants in a greenhouse on his 500-acre High Park Farm, a few miles from the town.

The former Beatle told waiting reporters that he was pleased with the outcome and that it could have been worse. “I was planning on writing a few songs in jail,” he conceded. “It would have been all right as long as I had a guitar.”
