How about;
We've are the greatest club in the world,
We've GOT Roberts and Tommy,
Lockers and Tomkins,
Paddy and Paul Deacoooooooooonnn.

These where the first names that came into my head! I like the one we sing now but they are all past players. We could also use the simple ones like;
"He runs to the left,
he runs to the righttt,
Amos Roberts,
he makes you look sh**e"
or maybe;
"There’s only one amos roberts,
one amos roberts,
he used to be sh**e,
but now hes alright,
walking in a wigan wonderland"

although "alright" is an understatement

Was at least 6 people singing in The Lord Rodney at Warrington. It would have been seven, but I didn't know the words.

Can't beat Ancient & Loyal for me. That is compulsory singing material.

I've never heard that sung at a game, but we should get it sung.

We should combine the two versions, I think 'Oh Campione' part is a bit rubbish.

I agree. IMHO "Oh Campione" has no relevance. I think it should be "Oh Wigan Rugby" as it fits in and goes with the second line "we are the Warriors".
