Gary Crosby was born on June 27, 1933 in Los Angeles and graduated from Stanford University. He entered the entertainment business and performed in a harmony singing group, The Crosby Boys, with his three brothers, Philip, Lindsay, and Dennis, during the 1940s, 1950s, and 1960s. As a teenager, he sang with his father on numerous records songs, and two of them "Sam's Song" and "Play a Simple Melody", became the first double-sided gold record in history. He also recorded duets with Louis Armstrong and at least one 45-single with Sammy Davis Jr.. He also performed on several variety programs, including ABC's The Pat Boone Chevy Showroom and NBC's The Ford Show, Starring Tennessee Ernie Ford. In the mid-1950s, Gary also had his own radio program, the Gary Crosby Show on CBS. The musical variety program debuted June 6, 1954, as a summer replacement for Bing Crosby's show.
As an actor, Crosby appeared in many television programs. On March 20, 1955, he appeared on the Jack Benny Program Season 5, Episode 13. Later, he was briefly under contract to 20th Century-Fox in the late 1950s. He appeared in a number of supporting roles for the studio, normally comedies in which Crosby played a soldier: Mardi Gras (1958) with Pat Boone; Holiday for Lovers (1959), as Carol Lynley's love interest; A Private's Affair (1959), with Sal Mineo; The Right Approach (1961) with Frankie Vaughan. Gary spent a small stint in the military where he was stationed with Elvis Presley whom he would make Girl Crazy with in 1965.
He is perhaps best-remembered for his recurring roles as Eddie the scheming bellhop on The Bill Dana Show and Officer Edward "Ed" Wells on NBC's Adam-12 from 1968–75, as well as appearances on several other shows produced by Jack Webb's Mark VII Limited (including an episode of Dragnet 1969 and five episodes of Emergency!). In addition to the aforementioned, he also appeared in three episodes of The Rockford Files.
In the 1970s, he appeared occasionally on game shows such as Match Game and Tattletales as a guest panelist. He married and divorced three times; he had one stepchild as a result. A lifelong alcoholic, Gary jumped at the change to write about his famous father. The children of other famous stars such as Christina Crawford (daughter of Joan Crawfrod) had made millions off of the tell-all tales of growing up famous.
In 1983, six years after his father's death, Crosby published an autobiography, Going My Own Way, which revealed the effects of his alcoholism and his difficult childhood as a result of his mother's alcoholism and his father's emotional and physical abuse. Some, especially his brother Phillip, said the abuse was not as severe as Crosby described. Gary himself reportedly admitted the book was a big exaggeration to make money.
In the late 1980s, Gary gained peace in his life and became sober. At the time of his death, he was planning a duets album with his father like Natalie Cole had done with her father Nat King Cole. Gary Crosby died of lung cancer in Burbank, California on August 24,1995, and is interred at Forest Lawn-Hollywood Hills Cemetery. Just like Gary Crosby made peace with his father, I feel I need to make peace with Gary's book. Who know how anyone would have turned out if they had Gary's life. The important thing is that he finally had peace at the end...
