Amazon.comPop has a good time eating itself on this collection of Doctor Demento favorites. The tunes on this stylistically varied double CD send up a plethora of pop culture phenomena. The perpetrators come from every imaginable entertainment background. Pro wrestlers, folk singers, comedians, actors, garage bands--you never know who's liable to produce a novelty song. Here it doesn't matter if a respected composer or a one-hit wonder recorded the ditty; all sorts of tracks jostle each other on this funny collection. The material covers quite a time span, ranging from Spike Jones's "Der Fuehrer's Face," released in 1942, to "Wappin'," an unreleased track by Darrell Hammond and Christopher Snell which was a hit on Demento's radio show at the tail end of the 1980s. The 20th Anniversary Collection is quite an assortment of the corny, goofy, wacky, and wild. --Fred Cisterna
