I love that! I'd been trying to think of a Villa song to that tune, and failed miserably. Mine went summin like "if the noses are there, there'l be stamping on heads". Yours is so much better!
Anyway, whats wrong with..
You are my Barry, my Gareth Barry,
You make me happy, when skies are grey,
you dont know dear how much we love you,
So please don't take, my Barry away...
Also, I know he's already got a popular song, but what about changing the words of "livin la vida loca" to "nigel reo-coker". Ah wel, its an idea.
