It's a blisteringly great sixties pop album, which apparently nobody but the Dutch were looking for in 1970. Perhaps its tuneful good vibes seemed inappropriate to the grim times of its release, when UK counterculture occupied itself with drying its drizzle-sodden greatcoat on the bedsit radiator and skinning up on the cover of Taste's On The Boards. Sinful Skinful is just way too happy, too melodic, too lovingly played and sung. Too pop.
If you don't have this already, prepared to be Blown Away (track 9).
