The 1st Singles Box is a box set compilation of singles recorded by the Who throughout their history. The album was released exclusively in the United Kingdom on 25 May 2004. It was considered the counterpart to the other compilation album by the Who, entitled Then and Now. The album was set with twelve compact discs containing two songs each, a la the A-side and B-side of the original single. Each individual CD was encased by a paper sleeve representing the single's original artwork from a particular country.
