I would have liked a mostly "mono" version of the "Past Masters" singles compilations, or at least a remastered re-release of the singles and E.P. box sets.
The Beatles had a habit of not including single cuts and b-sides on their British albums, and all their singles up to April 1969 are in mono.
All the singles (up to, but not including "The Ballad of John and Yoko", "Old Brown Shoe", "Something", "Come Together, "Let It Be") had originally been released in mono-only mixes on the 45s. Most of the stereo versions of these singles and B-sides were only mixed to stereo when these cuts were needed to be included on later stereo compilation albums, or international releases such as the butchered U.S.A. Capitol Records catalog of albums. The "Past Masters" set included mostly the afterthought stereo versions, and only a few mono versions for early songs (and one late era B-side) that had never been re-mixed into true stereo. As a fan of the mono versions, I would like to have the remastered mono versions of these singles and B-sides.
