This instrumental / vocal band known as the Keen Teens appears previously on some websites dedicated to doo wop groups, but once listened to, they were a band with chorus and that's not all 50's boy and girl groups they sang in a doo wop style even if they were quartets or quintets and in their photos they appear in a pose of a doo wop group, don't be fooled.
Band members first row; L to R; Max Harrington, Morris Alexander and Kirby Williams.
Back row L to R; Duian Bishop, Buddy Maynard and Mickey Jolly.
Listen to the Keen Teens and decide if they can be classified as a doo wop group, for me they are not.
