The Elvin 'Lighthouse' CDs were definitely issued as 2 separate CDs by BN around 1989 (ish). I have Vol 1 of this (now superseded by the Mosaic).
Other 'Doubletimes' include, I think, the Stan Kenton 'Innovations' set ( ). As mentioned previously the McIntyre was also a 2CD Doubletime, probably my favourite of these.
Just recently picked up the Grolnick ( ). Hiding in the shelves in a London store until I spotted it. Two great sessions on that one.
HMV have also been selling some of the 2CD sets at £4.99, including the Dorham, the Burrell and the Green/Clark. Bargain of the century !
