Roger Waters on first playing The Dark Side of the Moon for his wife

When the record was finished I took a reel-to-reel copy home with me and I remember playing it for my wife then, and I remember her bursting into tears when it was finished.  And I thought, "This has obviously struck a chord somewhere," and I was kinda pleased by that.  You know when you've done something, certainly if you create a piece of music, you then hear it with fresh ears when you play it for somebody else.  And at that point I thought to myself, "Wow, this is a pretty complete piece of work," and I had every confidence that people would respond to it.
