You're not singing any more: where do soccer chants come from?

Analysis: the chants sung by fans have their origins in hymns, opera, folksong, advertising jingles and nursery rhymes

I live in Phibsboro, on the northside of Dublin. On match days, I hear supporters singing chants as they walk past my front door on their way to Dalymount Park, which is hallowed ground in Irish soccer. I'm a composer and write a lot for choirs, and I can’t help noticing how well these groups, men mostly, sing. Their tuning, projection and conviction make for a powerful choral performance.
