Cowboy Killer
Only ever popped up in one song AFAIK

Unsurprisingly there are few of these in Fall songs:
Receptionist (Slang King)
Sports Reporter (Kicker Conspiracy)
Rector (Spectre vs Rector)
Rabbit killer (Jawbone and Air Rifle)
Solicitor (Solicitor in Studio)
Furniture salesman (Eat Y’self Fitter)
German athletic star (Athlete Cured)
Caterer (Das Katerer)
Shepherd (Theme From Sparta FC)
Stock Replacer (Senior Twilight Stock Replacer)
Bingo Caller (Bingo Master’s Breakout)
Scriptwriter, Soap Opera Writer (The Man Whose Head Expanded)
Estate Agent (Hit the North)
