5.5MB Windows Media Video
Yes it's big, but it's over 3 minutes long so it's actually very well compressed. Sorry to those who can't play .WMV files but any other format would've been 15MB or more.
It should be noted that the performance has not been edited at all, so you're seeing me complete with mistakes. :) But there weren't many and I was happy with it.
Also the audio doesn't pick up the dynamics very well - as far as the mic could tell, everything was loud. But trust me, there are dynamics in there that make it sound so much better.
