I Shall Be Released The Band recorded the first officially-released version of the song for their 1968 debut album, Music from Big Pink, with Richard Manuel singing lead vocals, and Rick Danko and Levon Helm harmonizing in the chorus. The song was also performed near the end of the Band's 1976 farewell concert, The Last Waltz, in which all the night's performers (with the exception of Muddy Waters) plus Ringo Starr and Ronnie Wood appeared on the same stage. Additional live recordings by the Band were included on the 1974 concert album Before the Flood and the 2001 expanded CD reissue of Rock of Ages.
