Wow Ian! Glad to hear that someone I know was able to attend that London event. There were many events and shows, like Elvis in Vegas, that I deprived myself from experiencing during a several year period all in the name of my start-up business that began just after Elvis' death in Aug. 1977.
BTW, neither my CD set nor WIKI made mention of the orchestra's name. Usually, that information is anxiously expressed. Can you remember which orchestra it was? Perhaps it was a group of musicians assembled by Jeff Wayne.
If you still have the vinyl copy, it must be worth some coin now. Thanks for sharing that adventure.
All Good Things, Robert
