theme as "Changes". "It's Gonna Be Me" is a ballad similar in style to Aretha Franklin. Originally titled "Come Back My Baby", it is lyrically similar to "Can You Hear Me?", in that it follows a casual seducer who realises the error of his ways and works to redeem himself. Biographers have generally praised the track as one of the most overlooked gems of Bowie's entire career. "John, I'm Only Dancing (Again)" is a radical seven-minute funk and disco reworking of Bowie's 1972 glam rock single "John, I'm Only Dancing". Although it mostly retains the original song's chorus, Bowie wrote new verses and an entirely different melody. Biographers have generally praised Bowie's vocal performance. It was released as a single in 1979. Release and promotion For the album cover artwork, Bowie initially wanted to commission Norman Rockwell to create a painting but retracted the offer when he heard that Rockwell would need at least six months to do the job. According to Pegg, another rejected idea was a full-length portrait of Bowie in a "flying suit" and white scarf, standing in front of an American flag and raising a glass. The final cover photo, a back-lit and airbrushed photo of Bowie, was taken in Los Angeles on 30August 1974 by photographer Eric Stephen Jacobs. Using that photo, Craig DeCamps designed the final cover at RCA Records' New York City office. Sandford calls it one of the "classic" album covers. After recording much of the album's material in August 1974, Bowie was eager to perform his new work live. Embarking on the second half of the Diamond Dogs tour, lasting 2September to 1December 1974, this portion has been given the nickname the Soul Tour, due to the influence of the new material. Because of this, the shows were heavily altered, no longer featuring elaborate set-pieces, partly due to Bowie's exhaustion with the design and wanting to explore the new sound he was creating. Songs from the previous leg were dropped, while new ones, including some from the new album, were added. During this time, a documentary was filmed that depicts Bowie on the Diamond Dogs tour in Los Angeles, using a mixture of sequences filmed in limousines, hotels and concert footage, most of which was taken from a show at the Los Angeles Universal Amphitheatre on 2September.
