yes I remember this as well, I also remember a tv program about it, or at least a part in a tv program.
Gatecrasher had big problems, and this tv program said that some Ibizan club night decided to call itself Gatecrasher, and there was nothing the real Gatecrasher could do about it, the Ibizan one even tried to sue if they carried on using the name, so they changed the name of the night they had at Pacha to Gatepacha.. there were other club brands as well, cant remember which ones though - does anyone else remember this program??
