In his sleeve notes for "The Bootleg Series Volumes 1–3 (Rare & Unreleased) 1961–1991", John Bauldie wrote that Pete Seeger first identified the melody of "Blowin' in the Wind" as an adaptation of the old African-American spiritual "No More Auction Block/We Shall Overcome". According to Alan Lomax's "The Folk Songs of North America", the song originated in Canada and was sung by former slaves who fled there after Britain abolished slavery in 1833. In 1978, Dylan acknowledged the source when he told journalist Marc Rowland: "'Blowin' in the Wind' has always been a spiritual. I took it off a song called 'No More Auction Block' – that's a spiritual and 'Blowin' in the Wind' follows the same feeling." Dylan's performance of "No More Auction Block" was recorded at the Gaslight Cafe in October 1962, and appeared on "The Bootleg Series Volumes 1–3 (Rare & Unreleased) 1961–1991".
