On the internet, no band is completely forgotten no matter how hard you might try. Adding my thr'penny worth to thise worth remembering:-

Be Bop Deluxe
Soft Machine
National Health
Kahn
Gilgamesh
Doctors of Madness

and, big at the time but rarely mentioned these days, 10CC

Until recently I would have added Dr. Feelgood to the list but their memory has flickered again recently with Julien Temple's wonderful 'Oil City Confidential'.
