Claim: Dancing Days, which was introduced by the band in concert well ahead of its commercial release, was largely dropped from concerts with the release of Houses of the Holy.
Evidence: "Dancing Days" is a song by English rock band Led Zeppelin. It appears on their 1973 album, Houses of the Holy, and was released as a single in the US. 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. 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.
