Late entry: Love the weekend song topic, and Eno's covered many from my youth (it's like you were there, man!). I'll add another that hits all the right notes, though not technically a "weekend" song. "Five O'Clock World" by The Vogues, though I have a version by Hal Ketchum.

But its a five oclock world when the whistle blows
No one owns a piece of my time
And theres a five oclock me inside my clothes
Thinkin that the world looks fine, yeah

Tell me that doesn't move you. Hal even throws in a little yodel on the end of the chorus that I don't recall from the original. Sets me free.
