The singer made an appearance during violinist Nigel Kennedy's Royal Albert Hall concert and belted out the song, which was first released four decades ago and re-recorded for Plant & Page's No Quarter album.

Plant's 18-minute performance on Tuesday marked the first time he has attempted the song live since Led Zeppelin's 2007 reunion at London's O2 Arena.

Plant also joined Kennedy for a cover of Jimi Hendrix's Hey Joe.
