Question: A 1944 collaboration of the Cow-Cow Boogie featured the American pop vocal group with lead singer Bill Kenny and which other artist?

<P0-S0> The Ink Spots were an American pop vocal group who gained international fame in the 1930s and 1940s. <P0-S1>  Their unique musical style led to the rhythm and blues and rock and roll musical genres, and the subgenre doo-wop. <P0-S2>  The Ink Spots were widely accepted in both the white and black communities, largely due to the ballad style introduced to the group by lead singer Bill Kenny. <SEP> <P1-S0> "Cow Cow Boogie (Cuma-Ti-Yi-Yi-Ay)" is a "country-boogie"-style blues song utilizing the folklore of the singing cowboy in the American West. <P1-S1>  In the lyrics, the cowboy is from the city and tells his "dogies" (motherless calves) to "get hip." <P1-S2>  The music was written by Don Raye, and lyrics were written by Benny Carter and Gene De Paul. <P1-S3>  The song was written for the 1942 Abbott & Costello film "Ride 'Em Cowboy", which included Ella Fitzgerald as a cast member. <P1-S4>  The first recording was by Freddie Slack & his Orchestra, featuring vocalist Ella Mae Morse in 1942. <P1-S5>  The record was the second release by Capitol Records and their first million-seller/ number one on the charts record. <P1-S6>  Morse learned the song from hearing Fitzgerald on a soundtrack she had acquired, even though the song had been cut from the movie. <P1-S7>  Morse also recalled recording the song in a single take, which she had thought was only a rehearsal. <P1-S8>  The 1944 collaboration between The Ink Spots and Ella Fitzgerald resulted in a number-one hit on the Harlem Hit Parade and a number-10 hit on the pop chart. <SEP> <P2-S0> William Francis Kenny Jr. (June 12, 1914 – March 23, 1978), known professionally as Bill Kenny, was a pioneering African American tenor vocalist with a wide vocal range spanning four octaves. <P2-S1>  Often regarded as one of the most influential high-tenor singers of all time, Kenny was noted for his "bell-like" vocal clarity and impeccable diction. <P2-S2>  Although he is most famous for his role as lead tenor with the Ink Spots, Kenny also led a successful solo career after disbanding the Ink Spots in 1954. <P2-S3>  Throughout the 1950s and 60s Kenny recorded, toured the world and appeared on many popular variety television shows. <P2-S4>  In 1966 Kenny became the star and host of his own musical variety show "The Bill Kenny Show" which aired on CBC. <P2-S5>  In 1989, 11 years after his death, Bill Kenny was inducted into the Rock and Roll Hall of Fame. <P2-S6>  Kenny is often noted as being the "godfather" of R&B tenor vocalists. <SEP> <P3-S0> Doo-wop is a genre of music that was developed in African-American communities of New York City, Philadelphia, Chicago, Baltimore, Newark, Pittsburgh, Cincinnati, Detroit, Washington, D.C. and Los Angeles in the 1940s, achieving mainstream popularity in the 1950s and early 1960s. <P3-S1>  Built upon vocal harmony, doo-wop was one of the most mainstream, pop-oriented R&B styles of the time. <P3-S2>  Singer Bill Kenny (1914–1978) is often called the "Godfather of Doo-wop" for his introducing the "top and bottom" format which featured a high tenor singing the lead and a bass singer reciting the lyrics in the middle of the song. <P3-S3>  Doo-wop features vocal group harmony, nonsense syllables, a simple beat, sometimes little or no instrumentation, and simple music and lyrics.
