Casio PT-1 Keyboard Demo song (Da Da Da)

Casio PT-1 Keyboard Demo song

I remember owning one of these.  I believe my parents got this keyboard for my brother and I.  I would play around with it all the time.  I fondly remember playing the demo song that was preset on the board. 

I also remember the song and the keyboard showing up in a Strong Bad Email.  Eh, Steve.

I love that this early keyboard has become a pop culture item of sorts.
