It certainly was a long time ago Hoot.
Giorgio did manage both Julie Driscoll and Brian Auger. I've just consulted a former collegue with a better memory than me and he remembers that Steampacket actually had three managers, Giorgio looking after Brian and Julie,others looking after Long John and Rod. This probably hastened their demise.
My business with the Malcolm Nixon Agency only started in 1964 and my dealings were always with George or Fionna, never met Malcolm. Of course as you worked there I may well have have run in to you when I called round to Conduit Street to pick up contracts or negotiate lower fees for groups who'd turned up late!
