You too can now buy an annoying tinny version of Barry Gray's classic theme for your mobile phone, designed to irritate the hell out of everyone around you.
I used to have a number of links listed, but frankly, the web sites spring up and disappear overnight and I'm fed up with keeping track of them... so you'd be better off with a Google search.
There are several different versions of the theme available of varying authenticity, so take your pick!
