Re: a tab for Blackwaterside. I tabbed this around 2003 or so and uploaded it to Usenet from where I guess it ended up on most of the tab sites. The tab was fairly decent (and you'll probably find it everywhere if you Google), but as part of the team who worked on the official book of Bert Jansch transcriptions a few years ago, we revisited the piece and a much better tab resulted - rare videos of Bert playing it had become available since I first tabbed it, enabling us to see that he fingered a few things differently. The book is called "The Bert Jansch Songbook," is very well tabulated and notated and is available on Amazon.
