Bill has gone to Firebird, a bluesy sorta band, Jeff has retired from music, and Ken sadly had that brain tumour, but in the recent interview on Earache site he seems to be getting much better now so thats great cos he's awesome!
Jeff Walker is an accountant, Bill Steer has his blues/rock band Firebird, and Ken Owen is starting to get back into music, and is still recovering from the brain tumor.
There is a really shitty interview somewhere on the Earache site from not too long ago, if you can get past the chimp quality writing (or editing, not sure who the culprit was ), it has some decent information.
