Elvis Presley - I Got A Woman / I'm Counting On You 20-6637, 78 RPM, US, 1956

Originally written and recorded as a rhythm and blues hit by Ray Charles in 1954, Elvis famously injected it with his signature high-energy rockabilly style. This 78 RPM single was released simultaneously alongside the 45 RPM format as part of RCA's massive marketing push following their acquisition of Presley's contract from Sun Records.
