On Her Majesty's Secret Service (Propellerheads) Easter Egg - Hidden Title Reference

This is simple enough... just put the song on... at about 0:21 there starts a beeping techno-esque noise which continues on and off throughout the song, which you'd think was just there as background. However, if you listen to it closely, and have a vague knowledge of Morse Code, you'll find out that this spells out 'OHMSS' ... On Her Majesty's Secret Service.

Neat eh?

For those of you with no clue....
O = - - -
H = . . . .
M = - -
S = . . .
where - is a dash and . is a dot (natch!)
