Lyric discussion by porridgebird 

This is one of those songs with upbeat music and sinister lyrics. The exact nature of those lyrics eludes me, but I think the general gist is:

"Five killed in a car crash": Fifi is a Scandinavian girl who caused a car crash for a family of five and dumped their bodies in a river; "Five poisoned over dinner": Jeremy is a London guy who poisoned the five members of his family; "I am Mad from Scandinavia/I want a guy in the London area": Jeremy and Fifi meet through lonely hearts ads; "You've got to conclude she just hasn't a heart": there's a media circus once they're accused, and the viewing public doesn't know how to react.

Beyond this outline, other references and contexts may have to be filled in. I know the title "Five Get Over Excited" to be a parody of the titles of Enid Blyton's whizzo jolly good 'Famous Five' novels about four kids and a dog who solve mysteries. I feel a connection may be made to Jeremy Bamber, a man accused of shooting and burying his five family members in the months before this song was released. But the name Fifi doesn't ring any bells for me, and neither verse sounds like the Bamber case anyhow.

@porridgebird James Dean died in a car crash, that's the reference there.
