hard rock sections with electric guitar that are performed by the whole group, thus more than doubling the length of Baez' original. When the recording appeared on their 1969 debut album, the credit read "Traditional, arr. by Jimmy Page" following the unspecified (at the time) authorship of the track on Baez's album. In the 1980s, Bredon was made aware of Led Zeppelin's version of the song; since 1990, the Led Zeppelin version has been credited to Anne Bredon, Jimmy Page, and Robert Plant. Bredon received a substantial back-payment of royalties. The band played this song at Led Zeppelin concerts on its 1969 concert tours; a filmed performance at Danmarks Radio, Gladsaxe, Denmark, on March 17, 1969, is included on the Led Zeppelin DVD (2003). For their 1998 reunion, Page and Plant performed a 9-minute version of the song. Plant has performed the song as a solo artist and with his bands Strange Sensation and the Sensational Space Shifters. As of 2002, the 1969 promotional EP using the song as the A-side track and "Dazed and Confused" as B-side had been one of top ten Led Zeppelin music collectibles. A collector, Rick Barrett, dedicated to his Led Zeppelin memorabilia, sold several copies of the promo EP for –500 each, "depending on the condition of the sleeve and of the record itself," said Barrett.
