I call this one 'Murray Mint'
I've used the Murray Gold Series Two closing theme as the main base, and have then added elements of the Dominic Glynn and Derbyshire themes. I then added some distorded echoes to each element. It was then speeded up, then slowed down, both at variable rates. A few final adjustments were made, plus some small Howell elements were thrown into the mix, and.......well, here it is!
It's took a fair few hours, but I think it sounds *complete* now
Here it is - Enjoy!
