I used to believe that the text in "Blue Da ba dee" by Eiffel 65 went: I´m Blue, in Aberdeen I will die, in Aberdeen I will die, in Aberdeen I will die... ;) How stupid!
A childhood belief about misheard lyrics

- Eifel 65 - Blue
I'm Blue (if I was green I would die...)
[I'm blue, da ba dee, da ba di.]— Matt - You know the eifel65 song "Im blue da be da ba di"
