You just need an MP3 file, somewhere to store it, and a link. A website is a good place, and there's lots of s/w out there with instructions that will enable you to build it. It's easier that it sounds. I'm sure we'd all love to hear you, and very likely, one day, we shall. I hope it's Sparrow's 'Three Coins In The Fountain' - I like that one.

One of my oldest friends, Maria, is half Chinese and half Trinidadian.

I'm a Yorkshireman, and songs from Sussex or from Norfolk sometimes seem to speak with a different voice, as it were. Quite interesting.
