Flogging a Dead Horse collects the A- and B-sides of the Sex Pistols' seven British singles.
It's not really the best way to hear those singles, though -- there was a sharp decline in the quality and relevance of the Pistols' material when Johnny Rotten left the band, and some of the later goofiness dilutes the impact of early songs like "God Save the Queen" and "Anarchy in the U.K." It is a useful compilation in that two songs -- "Did You No Wrong" and "No Fun" -- are unavailable on both Never Mind the Bollocks and The Great Rock & Roll Swindle, and it is perfect for fans who don't want to sift through the latter and will be content with a brief overview.
Still, Dead Horse doesn't match Never Mind the Bollocks (still the necessary purchase) for start-to-finish venom, and as inconsistent as Swindle is, it can be quite entertaining.
So, Flogging a Dead Horse is not the best compilation, but it will do in some cases.
