Nights in White Satin was my choice as well - I loved that song when I was little and would get my mother to put Days of Future Passed on over and over again just because I wanted to hear the poem at the end and the gong.
(Note that although the album and single were released in 1967, it wasn’t until this year that it made the year-end chart, only making it to #103 in the weekly chart when first released. It was reissued in 1972 after the group had had several other hits, and made #2 that time.)
It’s a good song, but I have to mark it down because the singer slurs the lyrics to the point of complete incoherence. Even with the actual lyrics in front of me I can barely connect what he’s supposedly saying to the sounds coming out of the speaker. It’s like the song was specifically recorded that way with the intent to make people get the lyrics wrong.
In the #1 poll series we tracked all the #1s regardless of whether or not they came out in the year they hit #1 (“Red Red Wine” making #1 in 1988 after being released in 1982, for instance), and I’m sticking with that here. Nights was five years old, but this is the year it made a major impact on the pop charts, so it earns its place.
