Even I know what The Cavern Club is Tubes jeez.
Its where The Beatles used to play before they were famous. It got knocked down but I think its now in a building near where it used to be, or rebuilt on the site not sure. Used to get dodgy scousers selling normal bricks to tourists telling them it was a brick from the cavern club. Quality.
Hahahaha.
The look of confusion on their faces when they see a pack of bricks being dropped off the back of a wagon.
