UFO 2: Flying (sometimes called simply UFO 2 or Flying; also subtitled Space Rock) is the second studio album by English hard rock band UFO. It was released in October 1971 on the Beacon label. The album is distinctive for its title track, which was among the longest tracks recorded in rock music up to that point and easily the longest song the band ever recorded. The track finishes with a backmasked reading from Rudyard Kipling's Gunga Din, "Tho' I've belted you an' flayed you, By the livin' God that made you, You're a better man than I am, Gunga Din!", and a slowed phrase, "Yes we know, it's all been done before before before". Gatefold cover.
