 Am I Going Insane (Radio)

"Am I Going Insane (Radio)" is a single by the band Black Sabbath on the 1975 album "Sabotage".Although common conception is that the suffix "Radio" was said to be added to the title because it was made for the purpose of being played on the radio, drummer Bill Ward said that it was Cockney rhyming slang for "mental"--radio-rental.
