Skinny Pete plays it in the music store scene in Breaking Bad season 5 episode 3 (http://www.youtube.com/watch?v=CQlAmtWHPII) and he makes more mistakes than me.

The instrument is Clavia Nord Stage 2 using a sampled Yamaha C7 grand piano and a few touches of synth.

Updated with a better take with less reverb on Feb 23, 2014.

I took some liberties with it, replacing the chords on the left hands with mini arpeggios, and playing it on electric instruments. I call this take "Electrocution". :-) A little bit Vangelis-style.

The instrument is Clavia Nord Stage 2 using a sampled Rhodes Mark I electric piano set to low and a pulse wave virtual-analog waveform oscillator.
