Sammy Johns has written a number of hit songs for other artists, but the one he will always be remembered for is the one he recorded himself. "Chevy Van," a song about a loose-loving man who picks up a woman while he's on the road, struck a loud chord with listeners in the sexually liberated '70s when Johns released it mid-decade. His mellow and easy style made love that was free and easy seem natural when he sang, "We made love in my Chevy van, and that's all right with me." The singer/songwriter sold more than three million copies in 1975, and the single flew to the top of the charts. The following year, van sales soared.
