I know this is off-topic and probably not the KGB you're after but this was also the name of a 70s US 'supergroup' which floundered critically and commerciallly, despite boasting some pretty big names: Camine Appice (drums, vocals - ex Jeff Beck, Vanilla Fudge) Mike Bloomfield (guitar - ex Paul Butterfield Blues Band, Dylan, Electric Flag, Super Session, ) Barry Goldberg (keyboards, vocals - ex Electric Flag, solo); Rick Grech (bass - ex Family, Traffic, Gram Parsons and Blind Faith, the original supergroup), and Ray Kennedy - vocals (West Coast sessioner). So now you know!
