Chuck Berry’s ‘Maybellene’ recently turned seventy. Recorded on 21 May 1955 in a studio on the South Side of Chicago, it tells the story of a man chasing his girlfriend down the highway. He’s in a Ford V8, she’s driving a Cadillac. She’s cheating, the car’s overheating, he’s trying to catch her before she gets away for good. ‘Maybellene’ isn’t Chuck Berry’s best song but it was his first single. Without it there’d be no Bob Dylan. No rock and roll as we know it. It’s a miracle.
