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

 In the lyrics, the cowboy is from the city and tells his "dogies" (motherless calves) to "get hip."  The music was written by Don Raye, and lyrics were written by Benny Carter and Gene De Paul.  The song was written for the 1942 Abbott & Costello film "Ride 'Em Cowboy", which included Ella Fitzgerald as a cast member.  The first recording was by Freddie Slack & his Orchestra, featuring vocalist Ella Mae Morse in 1942.  The record was the second release by Capitol Records and their first million-seller/ number one on the charts record.  Morse learned the song from hearing Fitzgerald on a soundtrack she had acquired, even though the song had been cut from the movie. "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.  Morse also recalled recording the song in a single take, which she had thought was only a rehearsal.  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> 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.  Built upon vocal harmony, doo-wop was one of the most mainstream, pop-oriented R&B styles of the time.  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.  Doo-wop features vocal group harmony, nonsense syllables, a simple beat, sometimes little or no instrumentation, and simple music and lyrics. <SEP> The Ink Spots were an American pop vocal group who gained international fame in the 1930s and 1940s.  Their unique musical style led to the rhythm and blues and rock and roll musical genres, and the subgenre doo-wop.  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> 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.  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.  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.  Throughout the 1950s and 60s Kenny recorded, toured the world and appeared on many popular variety television shows.  In 1966 Kenny became the star and host of his own musical variety show "The Bill Kenny Show" which aired on CBC.  In 1989, 11 years after his death, Bill Kenny was inducted into the Rock and Roll Hall of Fame.  Kenny is often noted as being the "godfather" of R&B tenor vocalists.
