Bee Gees - i started a joke, 1968

"The melody to this one was heard aboard a British Airways Vickers Viscount about a hundred miles from Essen. It was one of those old four engine "prop" jobs, that seemed to drone the passenger into a sort of hypnotic trance, only with this it was different. The droning, after a while, appeared to take the form of a tune, which mysteriously sounded like a church choir. So it was decided! We accosted the pilot, forced him to land in the nearest village and there, in a small pub, we finished the lyrics [with Barry]. Actually, it wasn't a village, it was the city, and it wasn't a pub, it was a hotel, and we didn't force the pilot to land in a field ... but why ruin a perfectly good story?"
