The list in 'North West Air News' - at that time a paper based magazine, provides details of the aircraft at the Southport Air Show for 9th September 2000. There is, however, no written comment, although from another source it was a very wet year - which water-logged the beach sand rather than affected the actual flying.

I don't have lists for the next few years handy, though I suspect that G-OGEE only appeared on the beach just the once.
I was there in 2000, highlights being a spirited display by the Airtours Boeing 757 - not a regular air show display 'act' while the Swedish Vampire never became common sight at UK shows.
