A guy once came to work and said he got a real bargain on an album. What album? Deep Purple's Greatest Hits. I joked, "Oh, so it's single!" That got a round of laughter, but I had conveniently forgot about "Hush," which came out in 1968, years before "Smoke on the Water." I also didn't mention that I also owned that album, which I bought for "Woman from Tokyo."
