An original Mousketeer in 1955, Crawford has been an actor on stage, films and television. He received an Emmy Award nomination at the age of 13 for his role as "Mark McCain," the son of Chuck Connors on the television series The Rifleman, which originally aired from 1958-1963 on the ABC network. During this time, he had wide popularity with American teenagers and a recording career that generated five Top 40 hits, including the single "Cindy's Birthday," which peaked at #8 on Billboard's Top 40 Hit Chart in 1962. Crawford played "Horsey", Tommy Kirk's cowboyish sidekick in the 1965 movie Village of the Giants which also featured Joy Harmon, Beau Bridges, and Ron Howard. The Naked Ape, a 1973 film directed by Donald Driver — based on the book — starred Crawford and Victoria Principal. Crawford had a key role in the early career of Victoria Jackson, of Saturday Night Live fame; after appearing together in a summer stock production of "Meet Me in St. Louis," he presented her with a one-way airline ticket to California, encouraging her to try her luck in Hollywood. This led to her early TV appearances on The Tonight Show, before being cast as a regular on Saturday Night Live. Crawford is currently the leader of the California-based Johnny Crawford Orchestra, which specializes in traditional jazz, early big band, and classical styles of music. He reconnected with his high school sweetheart Charlotte in 1990 and married her in 1995.[1]
