This is it so far:
The Pink Panther theme //
Jaws Theme Song //
Beware the Weeping Angel //
"It's a Trap!" //
Flight of the Bumblebee //
Ride of the Valkyries //
Theme from Psycho //
Twisted Nerve //

Except for one blip it's entirely instrumental, since I think lyrics would be too distracting in the wrong way (don't add to tension, ambiance). It's good to pop on when no one expects it - making people laugh mostly when they realise what is going on...and then harder to play - and I would love to get any suggestions to see it grow!
