Live aus dem Cascade Beat Club in Köln is one of the rarest albums by a hit British Invasion band released near the peak of its popularity. Its existence is unknown even to most Swinging Blue Jeans fans, and the material doesn't even appear on the otherwise thorough four-CD set of their 1960s recordings, Good Golly, Miss Molly! The EMI Years 1963-1969. Does that mean it's worth the hunt? Quite possibly not, though it's not without its merits. First, at least some of it sounds like it was recorded in the studio and subjected to some dubbing of live audience noise. In fact, a few of the tracks are definitely overdubbed versions of recordings that found official release as studio cuts. There are, however, a few songs that they didn't put on any other release in the 1960s, those being covers of "Kansas City," "Johnny B. Goode," Roger Miller's "King of the Road" and "Chug-a-Lug," Glenn Miller's "In the Mood" done Merseybeat style, and, even odder, the Beatles' "Eight Days a Week." "Tutti Frutti," "Shakin' Feeling," and "Good Golly Miss Molly" are sung in German, but these are obviously the studio recordings the Swinging Blue Jeans released for the German market overdubbed with live ambient noise. Of the songs not available elsewhere, actually the group does attack these with vigor, especially "Johnny B. Goode." In all, however, it has to be considered a very peripheral item, even for big Swinging Blue Jeans/Merseybeat enthusiasts. A CD reissue adds four bonus tracks, those being all four of the German-language studio recordings they did in which they re-recorded some of the songs they'd placed on their standard releases.
