I spotted this on MetaFilter: a superb and desperately sad article about the rise and fall of Bill Haley.

After ten minutes or so Billnitzer would bring him his food. But usually he was thinking about something, so he ignored it. After a while, though, he’d start to shift in his seat and look around. And then he’d start to hum. Billnitzer, refilling his coffee cup, knew the tune—everybody knew that tune. It was “(We’re Gonna) Rock Around the Clock,” the best-selling rock song of all time. She smiled, because she knew what he was doing. He was giving people around him clues. He wanted people to hear him and say, “You’re Bill Haley, aren’t you?”

But they rarely did.
