You see that's the problem/joy of the Manband, there are as many groups as there are individual fans! (And come to think of it, probably as many offshoot groups as there are fans).
But actually, now you mention it RobW, I'm kinda Group 7 myself - it was the whole raft of the extended Manband family that was always part of the joy of being into them - all the associated little alleys and cul-de-sacs down which to dive for an LP or two. Helps, Neutrons, Alkatraz, Iceberg, Happy Daze ... all good family fun.
