Marvin, Welch & Farrar (aka MWF) were a 1970s British and Australian popular music group formed by two members of The Shadows as a change of direction manoeuvre by The Shadows during 1970–73 . The distinction was that while The Shadows were famous for their instrumental work, Marvin Welch & Farrar were a (trio) vocal harmony group. They have been favourably compared to USA folk close harmony group Crosby Stills Nash and Young (aka CSNY) or The Hollies.
