Yeah! I ran to the street, looking for information...
I'm sure you are all aware of this by now, but BowieNetter, iforgot, has created a very useful and informative Riverside mini-site. You'll find pretty well everything you need to know on this beautifully designed site, including location (with a handy map), how to get there, and details regarding the pre-show meet up at the Old Trout pub in Hammersmith.
You can reach the site by clicking on the image above, and, as iforgot suggests, if you've not told him you intend to show up at the Old Trout yet, you really should, as he may be able to further negotiate something in your favour.
There will also be a post-show party organised by TVQueenBitch at Electric Dreams in Soho, that sounds like it will be much fun indeed. TVQueenBitch will be DJing a special Bowie set at the venue... in full drag! He has also negotiated a discount for BowieNetters. Click
