There was no ticket for the 21/06/1990 show in paris
It was a free concert for the music fest. All 21/06 of every years everywhere in France and in some country in the world ....
YES was the first part but they didn't play. They cancelled their show and the Cure Began his show earlier.
So , just one band this night : The Cure
as far I know i have always heard and read that on 21.06.1990 Paris concert, The The was schedulded as first band, not Yes.
the first band scheduled was "The the" not Yes ; anyway it was cancelled.
