to the rest of its parent album's dark atmosphere and themes. RCA issued Diamond Dogs on 24 May 1974 with the catalogue number APLI 0576. The album was a commercial success, peaking at number one on the UK Albums Chart and number five on the US Billboard Top LPs & Tape chart. A $400,000 advertising campaign featuring billboards in Times Square and Sunset Boulevard, magazine ads, subway posters declaring "The Year of the Diamond Dogs" and a television commercial, one of the first of its kind for a pop album according to Pegg, boosted its sales in the US. In Canada, it repeated its British chart-topping success, hitting number one on the RPM 100 national albums chart in July 1974, remaining there for two weeks. RCA released the second single, "Diamond Dogs", on 14 June 1974, with a rerecorded version of Bowie's 1971 single "Holy Holy" as the B-side. It was Bowie's least-successful single since "Starman", peaking at number 21 on the UK Singles Chart and failing to chart in the US. "1984" was released as the third single in the US and Japan, but failed to chart. Reviewing the single in August 1974, Billboard described "1984" as Bowie's "most commercial cut ... in a long time". Tour Bowie supported the album on the Diamond Dogs Tour, whose first leg lasted from 14 June to 20 July 1974. Co-designed and constructed by Chris Langhart, it featured elaborate set-pieces and cost $250,000. Fritz Lang's Metropolis (1927) and Robert Wiene's The Cabinet of Dr. Caligari (1920) influenced the tour's design, primarily due to Bowie's interest in German expressionism. The tour's second leg, from 2 September to 1 December 1974, has been nicknamed the Soul Tour, because of the influence of the soul music Bowie had begun recording for Young Americans in August. The shows were altered heavily, and no longer featured elaborate set-pieces, partly because Bowie had tired of the design and wanted to explore the new sound he was creating. Bowie dropped songs from the previous leg, while he added new ones—some from Young Americans. In early September, director Alan Yentob filmed a documentary that depicts Bowie on the tour in Los Angeles, using a mixture of sequences filmed in limousines, hotels and concert footage, most of which was taken from a show there at Universal Amphitheatre on 2 September.
