"One Day", by The Cannanes. It's funny what can pop into your head. The album on which this little number is something of an afterthought, "The African Man's Tomato" (aka "Lord Nelson's Seafood Capers"), is one of the unsung Australian rock masterpieces. Ask any of the twenty people who own a copy. It changed my life. (And I don't say that lightly, no I don't.)
The Cannanes, bless their cotton socks, are still at it, too. Not that you'd know.
