Cover art for Edmonton lyrics by Rural Alberta Advantage, The

under the lights at the edge.

this song is my favorite... when the laaaaate at night part starts i freak out like a spider monkey.

It is "the lights at the Leg" (rhymes with edge). Refers to the Legislature Building and something Edmontonians call purple city.

At night, I think all year round but maybe just in the summer, the Leg is illuminated with purple floodlights.

actually, it's illuminated with yellowish lights. purple nights refers to staring into the lights for about a minute, and then when you look away all of the other lights int he city appear purple. try it sometime ;)
