Only taken two years to finally get around to.
I put this off mainly due to the sheet music being affordable and easy to get - it's only fairly recently I noticed that Oskar was bundling Matilda's sheet music into a larger bundle that cost more than it used to, hence why I felt okay about making a tutorial for it at long last.
You can find the sheet music bundle here:

DISCLAIMER: I learnt this by ear - everything in the video is just what my ear thinks of what I hear and what my eyes can see in his live recording, nothing more.. I learnt it in a month, played it like that for a year, then realised I had missed things out and had to re-learn it.. so it's possible I still haven't got it 100% right.
Just wanted to (albeit late) give those screaming for a tutorial, something to go on at last.. but honestly, half the fun is working it out, people!
