Paul Samuel Whiteman was an American composer, orchestral director and violinist as well as being the leader of one of the most popular dance bands in the United States during the 1920s and 1930s. Bing Crosby and Al Rinker had been together in a Jazz band in Spokane, Washington while in college. However, the band was so popular that the two dropped out of college and drove Rinker’s Model T to Los Angeles where Rinker’s sister, Mildred Bailey, who was a Jazz singer, was working. Shortly after their arrival in Los Angeles they landed a gig on the vaudeville circuit, as a vocal act. Some members of Paul Whiteman’s Orchestra caught their act and recommended them to Whiteman. Nothing appears to have happened.
Don Clark was a former member of the Whiteman band and, in 1926, offered the two individuals that were waiting & hoping to join Paul Whiteman the chance to make their first record.
They said ‘YES’ and, on Monday 18th October 1926, accompanied by Don Clark’s Biltmore Hotel Orchestra in Los Angeles, Bing Crosby and Al Rinker recorded “I’ve Got the Girl”. The song was recorded using an electrical, not acoustic, microphone and “I’ve Got the Girl” was released on a 78rpm disk as Columbia #824-D. On the flip side was Don Clark’s instrumental version of “Idolizing”. Two months later Bing and Al joined the Whiteman Orchestra in Chicago, where, on December 22nd 1926, they cut their first records with Whiteman — “Wistful and Blue” and “Pretty Lips”.
I think it’s safe to say that the ‘rest is history’.
