Actor and Entertainer. One of Bing Crosby's four sons from his first marriage to Dixie Lee (brothers Gary, Lindsay and twin brother Dennis are all deceased). He entered showbiz with his brothers in the 1950s forming a nightclub act called the Crosby Boys that performed in Las Vegas and elsewhere. He made some recordings and had small roles in films such as "Robin and the 7 Hoods" and "None But The Braves." But like his brothers, was plagued with various problems like alcoholism and depression as an adult (two of the brothers committed suicide). Philip was found dead on in his Woodland Hills, California home of unknown but natural causes at age 69 (findagrave.com)
