Looks very much like it is (I genuinely love that old rogue). Joseph Francek is probably Scholz according to Discogs and Alberto Lizzio is a pretty well-known pseudonym of his. Paul Kantschieder and Carl Michalski seem to be real people, but little-known enough to be probably targets.
But I wouldn’t put too much faith in AcoustIDs, they might be attributed incorrectly. Peter Falk seems to be a real person, with his own website. I would add a new release with separate recordings.
I’d take them with a grain of salt in general, but if you have the ability to verify them yourself on the different releases they’re pretty trustworthy.
I’ve found many cases of AcoustIDs on the wrong recording but very few cases where there are actual collisions.
