Been scouring the UFOMIND archive where I'm sure I saw the original reference.  While I still haven't found the original announcement, this is a very close "second" confirmation:

Dr. Steven Greer, CSETI, Admits His Connection With Lawrence Rockefeller

Dr. Steven Greer, who in recent months flew to England to obtain a clear
vivid video tape of a disk pulling aerial manuevers from an English couple
and flew back to the US, refusing to show anyone the video, was on the
Starfire Radio Program on Cable News Network on Nov 31st. When asked about
the video tape, Greer stated that he had even better videos, but was saving
them for Project Starlight, and indicated that none of the
superlative videos would be released to the public. When asked how an
apparently "poor country doctor" could afford to flit around the world and
do all these things, Greer several times raised the fact of his friendship
with Lawrence Rockefeller. While not a surprising revelation, this public
statement ensures that Greer will now be counted among the ranks of those
participating in the global coverup of information related to this issue,
and adds his name to the long list of New World Order control factions
determined to keep the general public ignorant on the important issue of
interactions with other species.

No reply from him to me letter yet either?

Although Tilbury says it was an English couple, I'm sure it's the Scottish video.
