The correct answer is Ted Lewis!
Theodore Leopold Friedman, better known as Ted Lewis (June 6, 1890 – August 25, 1971), was an American entertainer, bandleader, singer, and musician. He led a band presenting a combination of jazz, hokey comedy, and schmaltzy sentimentality that was a hit with the American public. He was known by the moniker “Mr. Entertainment” or Ted “Is Everybody Happy?” Lewis. Lewis died of lung failure in August 1971.
