Pub at Nunhead.

My dad goes on and on about this. He tells me of a pub in Nunhead, which had a soundsystem compromising speakers attached to the ceiling firing downwards. He believes this was the best environment he has heard music in, such as Pink Floyd - Money, Time, and One of these days. He told me the sound from some speakers was different from others, so I surmised this must have been a quadrophonic setup.

Anyways, what I would like to know is if anyone here knows of this pub, or indeed if it still has this up and running?
