First we hear the rhythm guitar….

….then at 0.07, we get the lead. And at 0.18, they’re joined by the bass and drums to complete the classic Quo sound. It’s often derided but I love that three-chord simplicity. Along with Rossi and Parfitt, the sound itself has become a national treasure. I’ve picked this example because it first helped me understand which guitar did what. And also because my sister Caroline celebrates her birthday today. From London to Brighton via Barcelona, her life is more comedic and dramatic than any comedy-drama you’ll ever see on TV. But if it were made into a series, this would be the theme tune.
