One day, Ricky was annoyed because I hadn’t changed a broken string on the guitar. I said, “You should play it like that.” He scoffed it off. But the next time I went to his house, he was sitting on the edge of the bed, playing and laughing. He said, “I’ve just written the most stupid guitar riff you’ve ever heard.” And it was the “Rock Lobster” riff, played on five strings in an open tuning.
