This original version by J.J. Cale was released in September, 1976. Mr. Clapton released his version in November, 1977 on the Slowhand Album. John Weldon Cale , professionally known as J.J. Cale, was an American singer-songwriter, recording artist and influential guitar stylist. Though he deliberately avoided the limelight (being temperamentally averse to celebrity) his influence as a musical artist has been widely acknowledged by figures such as Mark Knopfler, Neil Young and Eric Clapton who described him as “one of the most important artists in the history of rock”. He is considered to be one of the originators of the Tulsa Sound, a loose genre drawing on blues, rockabilly, country, and jazz.
