Eclipse

The closing track on Pink Floyd's famous Dark Side of the Moon album, "Eclipse" seamlessly follows "Brain Damage" to close it out - radio stations almost always played the songs together. The album was well into production but didn't have an ending until Roger Waters came up with the song. It reprises some lyrics to the opening track "Breathe" ("All that you touch, all that you see") before closing out the album with the words, "There is no dark side of the moon really. Matter of fact it's all dark." This closing statement is the voice of Gerry O'Driscoll (often misspelled "Jerry Driscoll"), who was the doorman at Abby Road studios, where the album was recorded. His is one of many random voices that show up throughout the album; Waters recorded people around the studios, looking for spontaneous thoughts, and Driscoll, with his sincere delivery and Irish accent, made the finished piece. He can also be heard on the track "The Great Gig In The Sky" (the line that begins, "I am not frightened of dying...").

Dave Gilmour recalled to Rolling Stone in 2011: "I remember working hard on making it build and adding harmonies that join in as you go through the song. Because there's nothing to it - there's no chorus, there's no middle eight, there's just a straight list. So, every four lines we'll do something different."

The working title for the Dark Side of the Moon album was "Eclipse: A Piece For Assorted Lunatics." They began working on it during rehearsals for their concerts, and performed early versions live during shows in 1972. This was an era when bands could spend a year refining songs by playing them at concerts before heading into the studio. These days, any such performance would be quickly recorded and distributed.
