Reprise Records was started by Frank Sinatra in 1960 who sold it to Warner Brothers in 1963. In 1976, the Reprise label was deactivated by Warner Brothers and all of its roster (except Frank Sinatra and Neil Young) was moved to the main Warner Bros. label.
An unconfirmed explanation for this move is that Sinatra wanted to be the only artist on Reprise, and Neil Young is said to have been the only Reprise act who refused to agree to a change in labels.
