Not to go too off on a tangent, did the second remix set ever come out in the UK (with different tracks)?

Which second remix set? The only (non-bootleg) Orb albums I've got that could be described as remix sets are Aubrey Mixes: The Ultraworld Excursions, which, in a fit of market manipulation, was released and deleted on the same day in the UK, and The Orb Remix Project: Auntie Aubrey's Excursions Beyond The Course Of Duty, which consists of Orb remixes of other bands' tracks.

And I think Live 93 is the only non-bootleg live album (oh, apart from the Peel sessions).
