The Ink Spots were a popular black vocal group that helped define the musical genre that led to rhythm & blues and rock and roll, and the subgenre doo-wop. They and the Mills Brothers, another black vocal group of the 1930s and 1940s, gained much acceptance in the white community.

As "Jerry and Charlie", Daniels and Fuqua had formed a vocal duo performing in the Indianapolis area around 1931. About the same time, Jones and Watson were part of a quartet, "The Four Riff Brothers", who appeared regularly on radio station WLW in Cincinnati, Ohio.

In 1933, that group disbanded, and Watson, Daniels and Fuqua got together to form a new vocal, instrumental and comedy group, which was initially called "King, Jack, and Jester". They continued to appear regularly on radio in Ohio, and became a foursome when Jones was added to the group the following year.

In July 1934 they accepted a booking at the Apollo Theatre, New York, supporting Tiny Bradshaw. At that point they changed their name to "The 4 Ink Spots" at the request of bandleader Paul Whiteman, to avoid confusion with his vocal group "The King's Jesters".

They first recorded for Victor Records in 1935, but although the group was growing rapidly in popularity their early record releases were not commercially successful. The following year Daniels left, and was replaced by Bill Kenny (b. 12 June 1914, Philadelphia, Pennsylvania - d. 23 March 1978, Vancouver, British Columbia). Also in 1936, they appeared on the first NBC demonstration television programmes.

For the next two years, their popularity grew through radio programs and tours. After a series of unsuccessful recordings for Victor Records and Decca Records, they had their first smash hit with "If I Didn't Care", a song written by Jack Lawrence, on Decca, in 1939.

They released such other Decca singles as "Address Unknown" (1939), "My Prayer" (1939), "When The Swallows Come Back To Capistrano" (1940), "Whispering Grass" (1940), "Do I Worry" (1940), "Java Jive" (1940), "Shout, Brother, Shout" (1942), "Don't Get Around Much Anymore" (1942), "I Can't Stand Losing You" (1943), "Cow-Cow Boogie" (1944 - with Ella Fitzgerald), "Into Each Life Some Rain Must Fall"/"I'm Making Believe" (1944 - both with Ella Fitzgerald), and "The Gypsy" (1946).

Many of these records made # 1 on early versions of the US pop charts - "The Gypsy" was their biggest chart success, staying at the # 1 position for 13 weeks.
