Clark Yocum (Vern Yocum's younger brother) is best known as guitarist and singer with Tommy Dorsey. A tenor, he was both back up singer and room mate for Frank Sinatra, joining THE PIED PIPERS in 1940. Yocum shared the lead with Jo Stafford and later June Hutton to create the legendary sound. It was a perfect blending of voices, which drew a national following, making them the best selling American group from 1945 to 1949. They appeared in many films, including "Las Vegas Nights" and "Ship Ahoy." Merging their sound with Johnny Mercer, they supported his venture to establish Capitol Records. Yocum became a "first call back-up-singer" in the 50's when rock 'n roll took over the market, accompanying major pop recording artists singing "ooh-ahs" and "doo-waps" in the background. The Pied Pipers made a five year tour with Frank Sinatra Junior across America, Europe, South America and Asia. Yocum later went to work for the American Federation of Musicians (AFofM) Local 47 handling contracts and regulating and monitoring recording sessions. He retired in 1977 and, after a long struggle with Diabetes, died at the age of 80 in 1993.
