From the wiki: “First recorded by Little Willie Littlefield the same year, ‘Kansas City’ later became a #1 hit when retitled and recorded by Wilbert Harrison (‘Let’s Work Together‘) in 1959 and, then, went on to become one of Jerry Leiber and Mike Stoller’s most recorded tunes, with more than three hundred versions, with several appearing on the R&B and pop record charts – including five separate singles released the same week in 1959, four of which charted on the Billboard Hot 100.
“Through a connection to producer Ralph Bass, Leiber and Stoller wrote ‘Kansas City’ specifically for West Coast blues/R&B artist Little Willie Littlefield. Littlefield recorded the song in Los Angeles in 1952, during his first recording session for Federal Records. Federal’s Ralph Bass changed the title to ‘K. C. Lovin”, saying he considered it ‘hipper’ than ‘Kansas City’. Littlefield’s record had some success in parts of the U.S., but it did not reach the national chart.
