"There's a neat little lass and her name is Mari mac..."

goes on like that

there's a neet little lass and her name is mari mac..

that one...much appreciated if you can help me out

There's a neat little lass and her name is Mari Mac
Make no mistake she's the girl that all attracts,
Lots of other fellas try to get her on her back,
But I am thinking that I'll have to get up early
Ha udil lat til lat il dum

Now Mari and her mother are an awful lot together
People often wonder if it's Mari or her mother
Or both of them together that I am courting,

Mari Mac's mother's making Mari Mac marry me,

My mother's making me marry Mari Mac...

I hope this helps you out a bit...
