They are called subsequently, the Sutherland Brothers and Quiver, Quiverlands for short

British folk/rock group formed around the core of Scotland-born brothers Gavin and Iain Sutherland.

Initially active as part of the band A New Generation in the late sixties, the siblings eventually were signed to Island and re-invented themselves as the Sutherland Brothers Band, releasing one album under that name in 1972. Sophomore album "Lifeboat" (recorded with different backing musicians) was billed simply as Sutherland Brothers.

In 1973 the pair merged with the group Quiver. This partnership, known as Sutherland Brothers & Quiver, was to last for several albums, tours, and a few chart hits.

By 1979 the brothers had parted company with the last remaining member of Quiver, Willie Wilson, and continued on as the Sutherland Brothers, releasing swansong album "When The Night Comes Down" later that year.
