Soundtrack to my life...

My favourite coffee mug has the following printed on it. This is the soundtrack of my life:

Dum-dum de dum, dum-dum de dum, dum-dum de dum, diddly-dum,
Dum-dum de dum, dum-dum de dum, dum-dum de dum, diddly-dum,
Dum-dum de dum, dum-dum de dum, dum-dum de dum, diddly-dum,
Dum-dum de dum, dum-dum de dum, dum,
Wah, wah, waaaaaaahh,
Waaaaah wahhhhhh,
Wah wah wah, wah wah-wah
Dum-dum de dum, dum-dum de dum, dum-dum de dum, diddly-dum...

As Rolf Harris would say, "Can ye guess what it is yit?"
