"Being one of the lucky ones, I attended the 1972 Filmharmonic Concert at RAH that this album was based on. More...
Prior to the album being released, Gordon Gray, who was A&R man at Polydor and in charge of the albums release, advised me over the phone that the arrangement of 'Zulu' played in the concert - much more dramatic and vibrant than the original, togeher with 'The Knack' and 'ipcress' were 'on the list' for inclusion on the album. Alas, they never made it.
So, I presume they are gathering dust somewhere, possibly never to be heard................ unless, of course Sony (Universal, ed.) have access to ALL the tracks recorded for the album and include them, but I'm not holding my breath!!"
