Goodwood.

I have a publication called Airshows 1978. It lists the participants for Goodwood - Sussex Air Pageant 6-7th May 1978.
It includes a flying F-15A 60053/BT from the the 36th FW at Bitburg.
There were quite a number of other participants too.
Looks like, you were not dreaming after all.
Hope this helps.
