May 28th, 1987:
In the US it was U2's "With Or Without You": Alright, I can deal with that. Not my favorite U2 song but at least it was a band I liked.
In the UK it was Starship's "Never Gonna Stop Us Now": Uh, WHO?
In Australia it was Dave Dobbyn With Herbs' "Slice of Heaven": Yeah, see, that's so totally out of left field that I don't know what to say.
