How to turn heads (part 1)

So the other day I was walking down a corridor at work (probably going for lunch or something, as I don't roam the halls usually) and for some reason I was humming to myself. A fact not weird by itself, but certainly something that will make people stare.

Especially if you are humming to the tunes of Andrew Lloyd Webers' 'Jesus Christ Superstar - Heaven on their minds'...
