Why Sanctuary would do this is sort of beyond comprehension.
This label normally assembles credible collections with decent documentation, and Neil Slaven's liners are usually tight enough to get to a track-by-track, or at least go into session details so one knows the origin of the material.
Men of the World is an aberration for a fine reissue label.
There is no track documentation other than names here, and one has to cobble the information together form other sources.
This three-disc set contains two discs of cast-offs and some of the session from what would result in Then Play On -- all of which have been released before on other compilations with better documentation.
As for the music, it's fascinating but unnecessary and reveals the troubled transition Peter Green was having with moving from the blues to his strange, ethereal, and mysterious pop.
The third disc in the set is another patchwork of cuts from three volumes of the Boston Tea Party dates.
Utterly avoidable.
