Two versions. The first is the Clancy's.

Oh, me name is Mick Maguire and I'll quickly tell to you
Of a young girl I admired, called Katy Donohue
She was fair and fat and forty and believe me when I say
That whenever I came in at the door you could hear her mammy say
Johnny get up from the fire, get up and give the man a seat
Can't you see it's Mr. Maguire and he's courtin' your sister Kate
Ah, you know very well he owns a farm a wee bit out of the town
Arragh get up out of that, you impudent brat, and let Mr Maguire sit down

Chorus
Diddle e dowdle-owdle-owdle
Diddle e dowdle-owdle-ow
Diddle e dowdle-owdle-owdle
Diddle e dowdle-owdle-ow
Ah, you know very well he owns a farm a wee bit out of the town
Arragh get up out of that, you impudent brat, and let Mr Maguire sit down

Now the first that I met her, was at the dance at Tarmagee
And I very kindly asked her, if she'd dance a step with me
Then I asked if I could see her home, if I'd be going her way
And whenever I'd come in at the door you could hear her mammy say
Johnny get up from the fire, get up and give the man a seat
Can't you see it's Mr. Maguire and he's courtin' your sister Kate
Ah, you know very well he owns a farm a wee bit out of the town
Arragh get up out of that, you impudent brat, and let Mr Maguire sit down

Chorus
Diddle e dowdle-owdle-owdle
Diddle e dowdle-owdle-ow
Diddle e dowdle-owdle-owdle
Diddle e dowdle-owdle-ow
Ah, you know very well he owns a farm a wee bit out of the town
Arragh get up out of that, you impudent brat, and let Mr Maguire sit down

Ah, but now that we are married, sure, her mother's changed her mind
Just because I spent the legacy her father left behind
She hasn't got the decency to bid me time of day
That whenever I come in at the door you'd hear the ould one say
Johnny come up to the fire, come up, you're sitting in the draft
Can't you see it's ould Maguire and he nearly drives me daft
Ah I don't know what gets into him, for he's always on the tare
Arragh just sit where you are and never you dare to give ould Maguire the chair

Chorus
Diddle e dowdle-owdle-owdle
Diddle e dowdle-owdle-ow
Diddle e dowdle-owdle-owdle
Diddle e dowdle-owdle-ow
Ah I don't know what gets into him, for he's always on the tare
Arragh just sit where you are and never you dare to give ould Maguire the chair

Another version

Oh, me name it is Maguire and I'll quickly tell to you
Of a pretty girl that I admire, called Kitty Donoghue
She's fair and fat and forty and believe me when I say
Every time that we go courtin' you could hear her mother say

Chorus
Johnny get up from the fire, get up and give the man a seat
Don't you see it's Mr. Maguire and he's courtin' your sister Kate
Ah, you know very well he owns a farm a little way out of the town
Will you get up out of there, and take the air, and let Mr Maguire sit down

Well the first that I met her, was the Pattern at Tralee
And I asked her very kindly, if she'd dance a step with me
She wanted to know if I'd see her home, and with her have some tea
Well I no sooner got inside the door when I heard her mother say

I asked her if she'd marry me, and become my darling bride
And we are going to tie the knot, before the next Shrovetide
When we're in our little love nest, we'll have currant cake and tae
We'll invite her mother to visit us, I'll imagine I hear her mother say

Regards Mick Bracken
