YNWA is just one of the things that makes lfc the best club in the world. no team will ever have an anthem like it.
Celtic have one just like it. I think another club does too can't think who they are. Jerry Marsden also did not invent it, it was from a 1945 musical.
Yeah it's Celtic's anthem too, but it'd be second to The Fields of Athenry for them. Which ironically we also use, as of the last few years.
It's such a special part of our football club though - it's something that i suppose it just taken for granted at this stage, but it will never get old, it just gives that special feeling before a game.
