Just to let you know that the Slammin' Vinyl site
(NEC Arena, Birmingham) seems to be suggesting that 808 will be playing live:
"For the first time ever we present the legendary dance pioneers 808 State playing some of their seminal tracks from 1990 and beyond."
Nicely worded, but it is Andy and Daz DJ'ing...
If I was in the UK, it sounds like quite a good event, however!
