I was convinced 5 was something to do with BEF / Heaven 17 / ABC but I've drawn a right blank. I'm going to assume that it's something Scottish and very hip c. 86!
10 I've got no idea on but could be something like The Floaters (see my ident!) or the Drifters.
Good luck to whoever takes up the mantle. I really must work......nnnnggggggggg
