The Free catalogue has recently been reissued with every album featuring an extra six or so tracks (on the same disc, tacked on after the final song), consisting of radio session versions, alternate mixes, unused tracks, etc.
The anniversary edition of Deep Purple in Rock that just came out has the exact same thing.
Maybe the ANATO release will be like this?
BTW are we sure this is actually going to happen? John S Stuart may have been 100% correct in believing that QPL were planning to release these special edition albums, but what's to say QPL won't change their plans?
