Snowcat - Done and thank you
Drassll - Thanks so much for pointing me in the right direction. It's a very helpful start. I'm trying to get the superbly over the top 80s style series one theme.
Basically I'm a performer and am wanting to (in part) play the Knightmare theme on a MIDI converted stylophone for the end of my new show 'Age of the Geek' that's going to Brighton and Edinburgh Fringes.
I'm still quite upset that whilst I'm old to enough to remember Knightmare, I was too young to go on it before it was cancelled 
This is my way of living the dream!
