Zig and Zag (and maths)

Ireland team to play Chile 1991

The Context:
Ireland, 1991. Lansdowne Road. A friendly against Chile. Some new buckos try their hand in the commentary booth and another begins his career on the field.

The Question:
(Ray D'Arcy, Zig and Zag) + (Bill O'Herlihy, Eamonn Dunphy and Johnny Giles) = what?

The Answer:
Billo Hurling, Amoan Grumpy and Johnny Styles.
An example:

Billo Hurling (lively, with brimming enthusiasm) "There now lads, the red carpet 'n all, ha? Now that's what I call fine treatment. What do you make of that then? Ha?"

(a pause, bordering on an awkward one)

Johnny Styles "They do have a beautiful kit though, there,  Bill, there. There."

Amoan Grumpy (dismissive with occasional sluring) "Here Stylesy enough of this poppycock. Leave it to the clowns in London and Paris to discuss that nonsensical nonsense.

(he squits at the moniter and becomes interested while nevertheless remaining incredulous)
Who is THAT bloke third from the front? A midfielder? With gel in his hair? Christ, this time Jack really has jumped over the fence."

Billo Hurling (chairmanlike) "Ah yes. His name is - "

Johnny Styles (unwittingly interrupting) "He's some lad on debut. Yeah from Cork I think. We'll be missing Chippy in the middle there. 

Amoan Grumpy (definitively) Definitely Stylesy. Right again.

Johnny Styles (turns mechanically to Billo) Yeh see Billo, the game of football has always been about gambles - there. As a manager all you can do is try to reduce the odds, there. With Chippy or with me the odds were reduced - greatly. But Jack's gamble with this Cork bucko is dodgey, 'n there. Our whinging hasn't really hurt Jack yet but some day he'll - "

Amoan Grumpy (wildly cutting across) "No n'ow n'ow n'OW Stylesy! (raises solitary finger) Just you remember baby: I'm not just a good whinger; (furiously shakes finger) I'm a great whinger. And if I wanted to (presses thumb to waggling finger) I could have Jack out of little Paddyland like (snaps fingers) that!"
