"Nights in White Satin" is a 1967 song by The Moody Blues, first featured on the album Days of Future Passed.It was not a popular title when first released. This was mainly due to its length, which at seven minutes and thirty-eight seconds was longer than the norm at that time. The song was re-released in 1972 after the success of such longer-running dramatic songs as "Hey Jude" and "Layla", and it charted at #2 in the United States. Its original release in the United Kingdom reached #19. The song was re-released yet again in 1979, selling even more copies.
