As with the single 's A-side , " Over the Hills and Far Away " , " Dancing Days " was introduced by the band in concert well ahead of its commercial release . Although a bootleg tape purports to prove it was first played at the Wembley Empire Pool in November 1971 , evidence suggests its inclusion on this tape was a hoax . The earliest live documented reference is in Seattle on 19 June 1972 where the song was performed twice : once during the main set and again as an encore ; it was then performed frequently during the rest of this tour , with a version appearing on the live album , '' How the West Was Won '' . With the release of '' Houses of the Holy '' , however , " Dancing Days " was largely dropped from concerts , although an abridged , acoustic version was occasionally performed during the 1977 U.S. tour . A full electric version was played as an encore on 13 July 1973 at Cobo Hall , Detroit , Michigan as featured on the " Monsters of Rock " bootleg
