I believe so yes. It was just never officially released.
As I understand it, Dogmatix (aka GRN and aka Jaded Alliance) did a full vocal mix and a dub mix. Only his 'Dogmatix Dramatical Dub' was released officially.
He also did a remix of A Little Respect which was 'exclusively' available on the old official website in the 'fan mixes' section, but is sadly no longer there.
