I thought Rowland sang "But you're dirty," too, if that helps. I just looked at the lyrics, and I'm really shocked. I think all I really got right was "Poor auld Johnny Ray," "Toora Loora Toora Loo-Rye-Aye," and "Come on Eileen."
But, if it makes you feel any better, yeah, you were clearly a huge pervert. OTOH, ever since I saw Maire Fahey in the video I've had a bit of a thing for chicks wearing only overalls. Maybe DMR corrupted the Youth.
