Now that picture is more like how I imagined from Ubonwans description and the sound file is exactly what I would hear in our bed room late at night and sometimes mid-morning. I have just downloaded it to minidisc to play in my bedroom here in Wales. I am kind of glad I didn't look behind the poster the time I heard it there and can understand why Ubonwan took a broom to investigate when I told her about it. Thanks for the link, I have been thinking about it for the last 4 months since I returned to Wales. เดวิด
