Recorded by Mary O'Hara and as found in her book, Mary O'Hara A Song For Ireland. I don't speak Gaelic, so I hope I've copied this down from the book without errors. I guess someone will let me know if I did.

HAIGH DIDIL DUM

Haigh didil dum, an cat is a mháthair
D' imigh go Gaillimh a' marcaíocht ar bhárdal;

CHORUS
Haigh didil dum, agus haigh didil dero,
Is haigh didil didil di haigh didil dum.

Haigh didli dum, do tháinig an bháisteach,
Hóbair go mbáifi an cat is a mháthair,

CHORUS

Haigh didil dum thug Walter dinéar dóibh,
Dreóilin beag rósta, 'gus smóilin is céirseach.

CHORUS

---
Haigh didil dum, the cat and his mother
Went to Galway riding on a drake.

Haigh didil dum, down came the rain;
The cat and his mother were nearly drowned.

Walter gave them a dinner,
A little roast wren, a lark and a thrush.

The next song in the book is The Little White Kitten. She tells this story: "Apparently this particular person [backstage] was a keen animal lover and was happily remarking on the number of nature songs and songs about animals in my repertoire. She enquired if I, by any chance had a song about a cat.
'Yes, indeed', I'm reported to have said enthusiastically, 'I have a beautiful song about a cat.' I was referring to 'An Caitín Bán'.
... 'I love cats', she said,'please do tell me more about the song.'
'Yes, I sang it in a competition when I was eight. I remember it well because I fell off the stage. As a matter of fact,' I continued cheerily, 'the song is about a dead cat.'
And there, abruptly the conversation ended."

She's referring to a different song that Haigh Didil Dum, but this is such a great example of her sense of humor, I had to share it.
