D.A.D.D by Kim Raymond in the 1987 Eagle Annual
Dial A Dawn Destructor (D.A.D.D) was a strip which ran in Fleetway's Eagle comic in the 1980s. It concerned the rather unlikely nocturnal crimebusting activities of pop group Dawn Destruction and its members: lead guitarist Big Chew Charley Carver, Harlem born singer Missy Troll, keyboard king Iceberg Slim Rodell and bass guitarist Girl Pete (who was a bloke). Their slogan was "The law's good, the law's the best, but if you've got a problem the law can't handle... ask DADD for help. Call Priory 743809... after dark."
And yes, we were indeed meant to take this seriously.
