A huge sheet of plywood covering the ancient snooker table props up two huge loudspeakers that pump out music generated by the two record decks that it also supports. The weather-beaten green side-door, the entrance to the room, is cheap, shabby and entirely appropriate. The room is not state-of-the-art, neither is it conventional in church terms. It is not luxurious, but comfortable. Not chic, but cosy. The Underground is the perfect venue for the youth outreach every Saturday and Sunday night.
