Those are the ones.  IIRC there are no new songs with Christian but several unreleased performances. The jam session with Prez  that was done for a radio show is terrific.

Wonder if these are the same tracks I listened to at the Harlem Jazz Museum back in 2006 - I particularly searched for Lester & Charlie material on their computer (and most of it was with the Benny Goodman band/small groups)

That's a very cute, romantic story; Yes, the Jazzland record is live material from 1948. The notes do not actually say where it was recorded. By the 1970s, when the "twofers" were appearing, Fantasy owned the catalogs of both Riverside/Jaazzland and Milestone, among others  

Solo Monk is part of this set; the other cuts are solo piano from all of his other Columbia albums.  There was a single sample disk, similar to Miles' Plugged Nickel:
