While most 12-year-olds engage in typical childhood activities, Johnny Crawford took on a different path. His early teens were spent starring as Mark McCain alongside Chuck Connors in ABC’s The Rifleman, following his earlier stint as a coveted Mouseketeer.

In the early ’90s, Crawford transitioned from acting to leading a vintage dance orchestra based in California.
