|"Immigrant Song", by Led Zeppelin|
Just six days after Led Zeppelin's appearance in Reykjavik, the band performed the song for the first time on stage during the Bath Festival. The song's lyrics are written from the perspective of Vikings rowing west from Scandinavia in search of new lands. The lyrics make explicit reference to Viking conquests and the Old Norse religion (Fight the horde, sing and cry, Valhalla, I am coming!). In a 1970 radio interview, Plant jokingly recalled: "We went to Iceland, and it made you think of Vikings and big ships... and John Bonham's stomach... and bang, there it was - Immigrant Song!
"Immigrant Song" is one of Led Zeppelin's few single releases, having been released in November 1970 by their record label, Atlantic Records, against the band's wishes. It reached #16 on the Billboard charts. Its B side, "Hey Hey What Can I Do", was otherwise unavailable before the release of the band's first boxed set in 1990. The single was also mistakenly released in Japan with "Out on the Tiles" as the B-side rather than "Hey Hey What Can I Do." That single is now a rare collectible.
