I mashed up a poem and song a couple of years ago, and I've recently dusted it off and tweaked it a bit, so it would be great if I could submit it for the challenge. I know Matt clearly states in the criteria that entries should comprise two or more songs, but I thought it was worth asking if my mash-up would be eligible.
(I'm assuming I'll be able to play it. Before I did the mash-up, I used to play the actual song using the island strum, which I swore off playing a couple of years ago. Re-learning the arrangement without reverting to the island strum is going to be a challenge in itself!)
That sounds great. Go for it!
