Under contract to the Los Angeles Philharmonic Orchestra, the Hollywood Bowl and LA Opera from 1985-1995 he sang with most of the world's great orchestras under most of the greatest conductors of our time. In 1994 Beckwith closed the book on the stage to try his hand at conducting choirs and orchestras. Beckwith is synonymous in Northeast Oklahoma for leading Handel's Messiah sing-along events at Christmas time since 2001.

He met his wife, Bartlesville's own Kathy Stewart, on the stage of the Los Angeles Music Center Opera in 1987. An Oklahoman since 1995, he now resides in Osage County, making beautiful music with Ms. Stewart and their adult daughter Megan.
