This is a classic.
Band member Justin Hayward wrote and composed the song at age 19 in Swindon, and titled the song after a girlfriend gave him a gift of satin bedsheets. The song itself was a tale of a yearning love from afar, which leads many aficionados to term it as a tale of unrequited love endured by Hayward. Hayward said of the song, "It was just another song I was writing and I thought it was very powerful. It was a very personal song and every note, every word in it means something to me and I found that a lot of other people have felt that very same way about it."
