Played a few times by Brian Matthew on Radio 2 Sound of the Sixties over the years. He'll probably play it this Saturday. I am not sure it was done under the Bowie name though. Or maybe it was - it was around the time of Laughing Gnome I guess
It was written by Bowie and recorded by Oscar who was Paul Nicholas under an assumed name. I've had it for years, first heard it on Sounds of the 60s about 1995.
