AceShowbiz - The original members of cult rock act Cathedral are reuniting for a one-night only show in London to mark their 20th anniversary. Lee Dorrian, Garry Jennings, Mark Griffiths, Adam Lehan and Mike Smail will perform their breakthrough album "Forest of Equilibrium" in its entirety at the O2 Academy in North London in December.

The current Cathedral line-up will also perform a second set at the anniversary show, according to Blabbermouth.net. Frontman Dorrian says, "We have come a long way since those dirge-ridden, smoke-filled, cheap-lager-and sweat-infested early rehearsals back in 1990."

"To be brutally honest, back then we never imagined that we would have continued on a 20-year journey and still be here to tell the tale," he added.
