This is the archive of two articles from http://skateandannoy.com. The first is a review of an album entitled "This is Skateboard Music". The review states:-
The only credible artist on the compilation is T.Rex. with his song "Skateboard" that appears in demo form at the end. Amazingly, this track may only be available on This is Skateboard Music." The second Archived article is a Blog entry from the same site by Kilwag and is worth a read too :-) Please note the videos embedded in the page don't work as this is a screen capture.
