"I'll post an address for the tune just as soon as I have a halfway decent recording of it."
Sorry about this, but it takes me a little time to get around to some of these things. The song is now finished and is indeed, the last track of "Travellers's Tales". I guess it is the one journey none of us will be able to recount ourselves.
As a couple of Mudcatters were kind enough to express interest in hearing the tune, I now have MP3s of it, which I am happy to send to anyone who still wants to hear it. It is a big file, over 5 MB, I think, so you will need to be able to handle bigger downloads.
It became the song, which Markus and I use as a show closer.
