You may like my version of the song - it's a combination of all the verses I've heard people do.

'Mrs. John Kirkpatrick' told me a couple of years ago that it isn't even Irish - it was written by an Englishwoman, but I've forgotten who!
Anyway, this is how I sing it...

Curragh of Kildare

Winter, it is past, and summer's come at last,
And the small birds are singing in the trees.
Their little hearts are glad, ah, but mine is very sad,
For my true-love is far away from me.

And it's straight I will repair
To the Curragh of Kildare,
For it's there I'll find tidings of my dear.

A livery I'll wear, and I'll comb back my hair,
And in velvet so green I will appear.
All these things I'll undertake all for my true-love's sake
For now is the springtime of the year.

Oh, tell me what went wrong when we both sang our love song
And we danced in the meadow night and day.
Was it really all that bad, did I make you very sad?
Will you come back to the Curragh of Kildare?

The rose upon the briar, and the river running clear
Bring joy to the linnet and the bee.
Their little hearts are blessed, ah, but mine can know no rest
For my true-love is far away from me.

Oh you that are in love, and cannot it remove,
I pity the pain that you endure,
For experince lets me know that your hearts are full of woe,
A woe that no mortal can cure.

I've not recorded this one yet, but intend to soon...
