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.
