King Adora is a British rock band, known for such songs as Bionic (2001), Big Isn't Beautiful (2000) and Suffocate (2001). The band broke up from 2005-2009, but is now back together and touring.
First time I ever heard it was in the hilarious and highly recommended Terry Pratchett book /Going Postal/. One of the characters is named (very ironically) Adora Belle Dearheart.
