Freddie Slack and singer Ella Mae Morse
"Cow Cow Boogie” is a "country-boogie" style blues song written for the 1942
Abbott & Costello film Ride ‘Em Cowboy. The first recording was by Freddie
Slack & his Orchestra, featuring 17-year-old vocalist Ella Mae Morse. The
record was the first release by Capitol Records and their first million-seller.
Although Ella Mae’s follow-up recordings sold fairly well, she never obtained
a huge following, but continued to make records until 1957. Morse died of
respiratory failure in Bullhead City, Arizona in 1999 at age 75.
