Wilfred Williams (December 28, 1910 – October 17, 1972) was an African-American singer. He had a successful cover recording of Fats Waller’s "I’m Gonna Sit Right Down And Write Myself A Letter" in 1957. The record sold over one million copies, and was awarded a gold disc. His trademark hook for his songs was to shout "Oh, Yeah" at the end of lyrics.
Born in Waco, Texas, Williams was the lead singer of the Charioteers between 1930 and 1950, when he formed his own Billy Williams Quartet with Eugene Dixon, Claude Riddick and John Ball. Many television appearances followed, including appearances on Your Show of Shows with Sid Caesar.
On April 5, 1959, the Billy Williams Quartet appeared on The Ed Sullivan Show and performed a rousing version of "Goodnight Irene".
By the early 1960s he struggled to retain his voice due to complications of diabetes. He subsequently moved to Chicago and sang on WGN-TV’s "All Time Hits" TV show (for which videotape exists) and spent time as a social worker until his death there in 1972 at age 61.
