Sean o Sé sings the Fahy version on his "Irish Heritage" album (1997)I've just noticed that he sings Fahy's English language verses along with the traditional Irish chorus, below (from Phillipa's post).

Curfá [chorus]:
Ó Maidrín rua, rua, rua, rua, rua,
An maidrín rua tá dána.
An maidrín rua 'na luí sa luachair,
Is barr a dhá chluas in airde.                                    

chorus
Oh! Little Red Fox, Rex Fox, Red Fox,
Oh! Little Red Fox, none bolder,
Little Red Fox, stealing through the rocks,
And the tips of his two ears peeping.

He seems to be combining the two versions, the old and the new, and very effectively too.
