You know, I've had this tab and one of Boom De Ya Da on Youtube open for (jesus) two months, but haven't done anything else because I'm a notorious laze-about. I'm trying to think what we'd need to do from here, aside from just making a post and asking for volunteers.
~ Expanding the backing track to be long enough for the actual song will be an eventuality, though the snippet might be best for now, since it's just to give the contributors a sense of rhythm. I'd prolly want to throw in more instruments to fill it out when I expand it anyway. ~ We'd need to write a third verse, wouldn't we? The original song had one, though we could get away with two if we really wanted to. (inviting bluefall to participate in this step, since she wrote what we have so far, would be an obvious courtesy to extend) ~ Images to use for the video seems like a thing it would be cool to open to the community to help contribute to. Making this a community-based collaboration is, well, pretty much why we'd want to do it anyway.
So about the only things I think we might need before going public are finalized lyrics and maybe some vocals samples to give everyone the general idea. After that it's all coordination and compilation.
