I am rushing out to the Góilín Singers' Club right now so I will get back to ye again about this I hope......
But what about 'ink o'er us' as a similar-sounding phrase for 'in chorus'?
I am not happy with this yet but don't have the time just now. I have a few more questions and suggestions of my own, but my pint is calling meeeeeee.........
I'll call again.
