Big Sandy & His Fly-Rite Boys is a western swing/country boogie musical band from California. The band is composed of Robert Williams, alias Big Sandy, Joe Perez, Ashley Kingman and Kevin Stewart.

They began as rockabilly revivalists in the late 1980s, then dug deeper into the music which rockabilly came from: western swing and particularly the country boogie style of the late 1940s and early 1950s, which served as a link of sorts between the western swing and rockabilly eras and was particularly associated with California country music in that era.
