This CD has two sides, so to speak.
On the bright side, its sound quality is much better than some reviewers make it out to be (in my humble opinion). Granted, it is not exactly high-fidelity (muddy stereo image, somewhat deficient bass and treble), but not very lo-fi either; I've heard bootlegs (see below) sounding much, much worse.
Artistically, it contains some interesting variations of well-known songs, along with renditions we already know from better recordings. Mr. Cohen is audibly a bit hoarse on some tracks, but gives a lively performance, vigorously backed by supporting singers and band. Hence my rating of four stars. In other words, not merely for completists.
On the dark side, it is doubtful that Mr.Cohen receives his due rewards for this performance... Officially, this CD is probably a legal edition--apparently, in the UK broadcasts from Canada of this period are in the public domain --but in my book, it is still a bootleg (which may readily be found on the Internet, by the way). Significantly, the sole copyright notice pertains just to the "package and artwork", not the music...
