Here's a song I got stuck in my head, unintentionally, though I suspect that's how all songs get stuck.
This one began when I was happily noodling around on Cm, the usual sort of pattern, Cm, Ab, Bb, or Cm, Eb, Bb etc.. except one time round the loop, I went Cm, Ab, 'G' .. now, I like finding places where I can get away with a single semitone chord transition, and Ab->G is one I've met before, so I should have been fairly immune to it.. until my RH ran down from Eb through a few notes, and a little voice at the back of my head sang 'def-end-ers of an-archy'..
That's when I knew I was doomed.
After spinning it round on the piano a few times, I ended up with this version.. which is quite removed from the screaming hockey stick waving high school terrors in the original =) Although if they want to come sing over this version, that's fine with me, provided they bring the uniforms!

I don't think I'm done with this one yet, I've found some nice chords for one part that don't really make much of an appearance in this version, a shame as they are quite nice & rich, but I'm suspecting the newer chords may call for a latin style rhythm.
