Late music legend John Lennon was convinced the American government bugged his house phone because it considered him a national threat.
The former beatle, who famously accused the US government of spying on him on Dick Cavett's TV chat show, believes he was a target because of his involvement in the peace movement during the Vietnam War.
In a 1975 interview with New York City-based Capital Radio which has only recently resurfaced, Lennon says, "I can't prove my phone was tapped. I just know there were a lot of repairs going on in the cellar.
"I know the difference between picking the phone up when it's working normally and picking it up and there being a lot of noises.
"I was paranoid at the time - who wouldn't be? Suddenly I realised this was serious; they were coming for me, harassing me. So I went on the Dick Cavett Show and I said it that night.
"I said it on the air and it went away the next day - nobody there. Now I think, 'Was I dreaming?' but my lawyer started to agree because his phones were also being tapped.
"As he's as straight as the next lawyer."
