"You'll Never Walk Alone" by Rogers and Hammerstein sung by Gregory Vanderlaan.

A heroic Ballad from the Musical Carousel. Famous for being sung by the fans of the Liverpool Football Club... and they perform on a Pink Floyd song "Fearless" from the record "Meddle." This one is sung acapella because it's simply too difficult to play on the guitar...
