Terry Gibbs reissue oddity

[Big Beat Steve]

That recent thread about "Moten Swing" prompted me to give Terry Gibbs' version issued on his "Lauching A New Band" LP released on Mercury in 1959 a listen again.

I have the Trip Jazz TLP 5545 reissue of that album. Putting Side 1 of the record on, something odd I had not really noticed before (or forgotten) became evident (had not listened to it for a long while; and if so, only Side 2 for his excellent version of "Jumping At The Woodside"):

Instead of the 6 tracks starting with "Opus 1" that are supposed to be there, Side 1 of that particular reissue inlcudes only 3 lengthy tracks by a trumpet-led quintet recorded live at some club. The first track is "Caravan" (NOT the Brown/Geller All Stars version also reissued on Trip) and then 2 ballads (the first one of which is an oft-reorded standard but I just cannot put the finger on the title right now).

I have no idea if the entire pressing run of this reissue has this fault but is there anybody who has this reissue and noticed the same discrepancy and is anybody who's heard this able to identify the actual recordings on Side 1?

I have a suspicion but the discographies do not bear this out so I am sort of stuck ...

Thanks!
