I would like to be able to sing a Scots song with it's correct pronunciation. My accent is Yorkshire+Durham, fairly Northern, but I am not Scottish.

Example 'Sheath and Knife'
"The broom blooms bonny, the broom blooms fair...
and we'll never go down to the broom anymair"

If I don't sing anymair it doesn't rhyme. But once I sing anymair rather than anymore should I be singing gang doon rather than go down, faither rather than father etc. But sung by a non-Scot this would be a mockery.
I don't know the answer.
