Nearly 50 years on, Marching Song remains a seminal recording not only of the ‘Jazz Britannia’ era, but of any time. Be it the epic scale, the sheer humanity, the passion of its delivery or the extraordinary playing of John Surman or the gone-too-soon Mike Osborne there's a multiplicity of layers that many have written of with greater insight than is possible here. Indeed, look no further than Duncan Heining's wise accompanying essay which rightly draws parallels with the art works of Nash and Nevinson, reminding us that Westbrook was and remains a painter in pictures as well as music. Here, the classic double CD is accompanied by an intriguing third of unreleased material, including an early (1966) version of the title cut, performed by a sextet of familiar names, including Surman and Osborne. It's rounded off by two pieces that featured Westbrook's work with Cosmic Circus that reflect his radical theatre experiences. ‘Marching Song’ rocks up, literally, on Live 1972 which is in effect the first Solid Gold Cadillac album, before Spedding joined and Phil Minton's vox roared on board. It works best as a fitting tribute to the spitting theatrics of George Khan and his battery of effects (credited as Nisar Ahmed Khan on Marching Song).
