Here’s a challenge with a less-involved set of criteria than meets the eye: examples of two or more officially released versions of the same song by an artist, not including live, orchestral, or simply remixed versions. As a final condition, you must state your favorite version.
I’ll start us off: Elvis Costello, “Black and White World” (Get Happy!! version and country-style alternate take, which was released on Taking Liberties). I prefer the alternate take.
