53. Elvis Costello and Burt Bacharach, "Toledo"
Two giants get together for an autumnal ballad of a middle-aged cad's regret – "Toledo" stands as a career peak for both Elvis and Burt. On their duet album Painted From Memory, they go together like Martini and Rossi on the rocks. Elvis and Burt consummated their partnership with a cameo in Austin Powers: The Spy Who Shagged Me, playing "I'll Never Fall In Love Again" while Heather Graham shimmies.
