You'll Never Walk Alone was written by Rodgers and Hammerstein for the 1945 musical Carousel, then became a hit in 1963 when Liverpool band Gerry and the Pacemakers released their version. Liverpool supporters at Anfield adopted it soon after, singing it before matches with scarves held high. The song, shortened to YNWA on banners and shirts, also became an anthem for Celtic, Borussia Dortmund and other clubs, and is now recognised far beyond football as a message of solidarity during hard times.
