Zoltan brings news of a live video, uploaded by YouTube user Tinhuviel that we’d previously missed! Here is Fluke playing Tosh (Skriekbackwash) live with Shriekback.
For those who would like a download: Shriekback.flv. Enjoy!
Edit
Tinhuviel has very kindly shared a higher quality rip of the video, which you can now download. Credit must also go to Shriekback and Barry Andrews... and, of course, Fluke. Thanks to all!
