I have mentioned this a bit but did want to be a bit more upfront about it as I am kind of pleased with it. I wrote and recorded a Glitch parody of This Land is Your Land (fortunately I believe the tune is out of copyright). It was recorded using my phone so the quality's not the greatest, but it's listenable!
It's on Soundcloud here. I would really like to know what you think!
EDIT: I recorded myself singing harmonies on this and created a me-and-me duet version! It's here.
