Episode 21 and the guys head back to Beerhouse for three beers on cask: the Pathfinder from Salopian Brewery, the Admiral Special Pale Ale from Tres Bien Brewery, and the Cleopatra from Derventio Brewery. Also, Ashley reveals his favourite song, Tom can't count and Mark....well, let's just say Mark probably won't look back at this episode with particularly fond memories..... Enjoy!
