Imports were selling well, so it was released in 1976. But my point is those songs were never intended by the band to be heard together on an album. Love Songs is no doubt an official release, but we never argue its merits versus say Revolver.
MMT has been loaded with hits by some marketting exec in Capitol, so of course it's going to sound good. (it's a great piece of vinyl)
Yesterday was released in the US as a single in 1965 and in the UK in 1976. It's an official release. But we would never (I hope) waste our time putting it in some "favourite singles" list, because the band never intended it to be one. Likewise Back in the USSR/Twist and Shout (Parlophone R6016 released 29/06/1976) which got to #19 in the UK charts. An official release, but surely no one here considers it a Beatles single as they do Help! or Paperback Writer.
In all my thirty years of Beatle following, it has always been the UK released, band sanctioned material that warrant any serious discussion/listing, not the whims of american record company employees. Otherwise releases from Argentina, Taiwan, Norway, Togoland etc would need inclusion, for they are as "valid" as US releases.
