Ernest Kador Jr. (February 22, 1933 – July 5, 2001), known by the stage name Ernie K-Doe, was an African-American rhythm-and-blues singer best known for his 1961 hit single “Mother-in-Law“, which went to number 1 on the Billboard pop chart in the U.S.
Born in New Orleans, K-Doe recorded as a member of the group the Blue Diamonds in 1954 before making his first solo recordings the following year. “Mother-in-Law“, written by Allen Toussaint, was his first hit, reaching number 1 on both the Billboard pop chart and the Billboard R&B chart. K-Doe never had another top-40 pop hit, but “Te-Ta-Te-Ta-Ta” (number 21, 1961) and “Later for Tomorrow” (number 37, 1967) reached the R&B top 40.
In the 1980s K-Doe did radio shows on the New Orleans community stations WWOZ and WTUL. The shows were known for his explosively energetic announcements and frequent self-promotion (occasionally causing problems for the noncommercial station). K-Doe’s catch phrases included “Burn, K-Doe, Burn!”, “I’m a Charity Hospital Baby!” and (addressed to himself) “You just good, that’s all!”. For a time he billed himself as “Mister Naugahyde”, until he was ordered to desist by the owners of the Naugahyde trademark. K-Doe then explained that it was a misunderstanding; he was actually referring to himself as “Mister M-Nauga-Ma-Hyde”, a word he invented himself.
