Definitely worth a read are the liner notes in which Jeremy Collingwood takes the reader back to an out-of-control sound clash in the United Kingdom of October 1974, an event that as a consequence of a series of misunderstandings ended in chaos and excessive police violence; a vibe perfectly captures in Junior Murvin's 'Police And Thieves', an excellent dub version of which can be found on 'Mr Perry I Presume'. The recognizability factor on this compilation is quite high, as in addition to obscurities like an a cappella version of The Gatherers' 'Words Of My Mouth' or an alternative mix of the great 'Ethiopia Country' by forgotten duo Peter & Paul, the track list of 'Mr Perry I Presume' contains the magnificent 'Groovy Situation' by Keith Rowe & The Upsetters , 'Keep On Moving', a melodica cut by Augustus Pablo & The Upsetters of the eponymous song by Bob Marley, a dubplate mix of Bob's 'Sun Is Shining' and a dub of Max Romeo's 'I Chase The Devil'. Another excellent selection from the inexhaustible treasure trove of The Upsetter!
