Not the most common chant. Personal favourite though.
Bertie Mee, Asked Bill Shankly, Ever heard of North Bank Highbury? Shankly: No i don't think so, But I've heard of the Chelsea, aggro... Chelsea aggro, Chelsea aggro, Allo, Allo. (Repeat til bored)
One of my favourites, catchy fanchant, good ringtone. (Ed: Better audio version of this classic added)
Hello, Hello We Are the Chelsea Boys Chant
Another classic and makes a good ringtone.
