This is ALMOST a straight reissue of their earlier "Cornology" 3 CD set which covered all five of the band's albums (if you discount the recent offerings from the "re-formed" band), and a few bits and pieces to pad out the third disc.
However, the tracks have all been remastered, and the difference is quite clear. The new versions sound clearer and a little louder. In addition, the tracks on the third CD have been re-ordered, so that their final album comes first on the disc, followed by the extras, unlike "Cornology", where it was placed rather incongruously midway through the disc.
As you probably know, the music is just tremendous. This set contains many of the funniest, most ridiculous songs you are ever likely to hear, anywhere. "Jollity Farm", "Hunting Tigers Out In Indiah", "The Intro and the Outro", "Mr Slater's Parrot", "Mr Apollo", "Canyons Of Your Mind" - all are wildly different, yet I would defy anyone to sit straight-faced through any one of them. Listen once to the sheer genius of Viv Stanshall, Neil Innes, et al, and you'll be hooked. Note also the excellent musicianship - this wasn't just a bunch of fools mucking about; these guys could really play, and some of their own compositions are rather fine pieces of music in their own right.
It's a pity EMI couldn't have come to an arrangement with the BBC for some of the few Bonzos tracks not included here, but get this and "The Complete BBC Recordings", and you'll have all you need from the funniest band of all time.
