The Mar-Keys, formed in 1958, were an American studio session band for Stax Records, in Memphis, Tennessee, in the 1960s. As the first house band for the label, their backing music formed the foundation for the early 1960s Stax sound. Their first and most famous recording was the organ- and saxophone-driven single "Last Night", it reached #3 Pop and #2 in the R&B charts in the United States. It also appeared on Last Night!, the first LP released by the Stax label. Selling over one million copies, earning certification as a gold disc. The lineup for this recording included the Royal Spades' Steve Cropper (normally a guitarist, here playing second keyboard; producer Chips Moman did not want a guitar part on the song), Packy Axton (tenor sax), Wayne Jackson (trumpet), and Jerry Lee "Smoochy" Smith (main keyboards), augmented by horn players Floyd Newman (baritone sax), Gilbert Caple (tenor sax) and others.
