There have been two Elmo Hope JRVGs.
The trio disc had 8 tracks, missing 2 tracks ("It's A Lovely Day Today" and an alternate take of "Mo Is On") from the session with Heath and Philly Joe. The quintet disc had 6 tracks, missing only an alternate take ("Crazy") from the session with Frank Foster, Freeman Lee, Heath, and Blakey.
The domestic had 20 tracks, 17 tracks from the two sessions mentioned above plus 3 tracks from a Pacific Jazz session from 1957 with Land, Stu Williamson, Vinnegar, and Butler.
The OOP domestic was available from Tower for quite a while but now I see it's no longer there.
