Williams played fiddle in Bill Monroe's band and with such notables as Mac Wiseman, Reno & Smiley, The Stanley Brothers, Flatt & Scruggs, Grandpa Jones, Jimmy Martin, Kitty Wells & Johnny Wright, Stonewall Jackson, and Marty Robbins.
The first time I saw him was in the late 60s just before Kenny Baker returned to the band, Benny was playing fiddle with his right hand bandaged where he had got it caught in the fan on the bus the day before.
His main instrument was fiddle but could play banjo, bass and guitar as well... Benny was a quiet and unassuming man and preferred to be the sideman and made many a country entertainer's song sound right.
Williams enjoyed a long-time collaboration with Scott's father Tom Morgan, himself an IBMA Hall of Fame inductee.
[citation needed] On this album, Benny plays fiddle on "Never Again" and "The Legend of Bill Monroe" and banjo on "Soldier's Joy".
