Hello.
Firstly, I know it's been done a number of times... like I said, I was encouraged to do it when I heard Kenny Ball's versions which are pretty similar.
I know all about the legality of the situation - I've just finished a law degree. However, that doesn't stop me from doing it anyway. The likelihood of Disney intervening is very low and if they do the worst they can do is tell me us stop (unless we pay royalties), or take our profits if the show's been done.
If you think the music's fine then that's great. It's a good start, at least. As you mentioned I haven't really tried to do anything superly original, but I'll think about it if the show becomes likely to happen. Actually, did you listen to Hakuna Matata? I went off on a bit of a tangent in the middle of that. Thought it was quite nice
Thanks for your comments!
