The Canadian singer, who is working on a new album, was out of the recording studio for six years until her return in 2011.
The Foo Fighters frontman gave a simple yet powerful performance.
Foo Fighter's frontman Dave Grohl paid tribute to a whole host of stars who have passed away recently, with a musical performance at last night's Oscars.
The star chose to cover the Beatles song 'Blackbird' during the 'In Memoriam' part of the show which paid tribute to stars like David Bowie, Wes Craven, Alan Rickman, Leonard Nimoy, Omar Sharif and other members of the film industry who died over the last year.
It was a simple sparse tribute but very moving none-the-less.
