When I was a lad, a tiny wee lad, my mother said to me,
"Come see the Northern Lights my boy, they're bright as they can be."
She called them the heavenly dancers, merry dancers in the sky,
I'll never forget that wonderful sight, they made the heavens bright.

Chorus:
The Northern Lights of Aberdeen are what I long to see;
The Northern Lights of Aberdeen, that's where I long to be.
I've been a wand'rer all of my life and many a sight I've seen.
God speed the day when I'm on my way to my home in Aberdeen.

I've wandered in many far-off lands, and travelled many a mile,
I've missed the folk I've cherished most, the joy of a friendly smile.
It warms up the heart of the wand'rer the clasp of a welcoming hand.
To greet me when I return, home to my native land.

The AB centers around the northern geomagnetic pole (not the same as magnetic pole, they're hundreds of miles from each other and move) and how far south you can see it depends entirely on time of year, light pollution, which part of the oval you are on (the AB is an oval, not a circle, extending from the NGMP, depends on time of day) and how active the sun is.

It's a good song too, for the curious
