Your Bird Can Sing" about Frank Sinatra after reading a hagiographic article on the singer in Esquire magazine. Written by Gay Talese, the article detailed Sinatra's wealth and power, describing him as "the fully emancipated male ... the man who can have anything he wants", and repeatedly mentioned his use of the word "bird" to mean a penis. Talese quoted a press release for Sinatra's upcoming TV special, which stated it was a show for those who were "tired of kid singers wearing mops of hair thick enough to hide a crate of melons", and he said Sinatra aimed to "communicate his talent to some rock-and-rollers – in a sense, he was battling The Beatles". Gould adds that while Lennon would have been amused to read about Sinatra having an assistant dedicated to maintaining his 60 "remarkably convincing" hairpieces, Lennon was piqued at the recognition afforded Sinatra, at the Beatles' expense, in the recent 1966 Grammy Awards. Singer Marianne Faithfull said the song was addressed to Mick Jagger and written about her, since she was Jagger's girlfriend (or "bird" in English slang) at the time. This interpretation was proposed by journalist Richard Simpson, and others have cited it as an example of the perceived rivalry between the Beatles and Jagger's band, the Rolling Stones. According to Beatles biographer Steve Turner, Faithfull's interpretation is incorrect, since she was not in a relationship with Jagger until later in 1966. Some writers have speculated that Lennon's lyrics were directed at Paul McCartney. According to Rolling Stone, and supported by Womack, the line "You say you've seen seven wonders" could be a reference to a comment McCartney made in 1964 when the Beatles were smoking cannabis with Bob Dylan in New York. Under the effects of the drug, McCartney declared that he knew the answer to the questions of existence and told Beatles roadie Mal Evans to write down any statements he made on the subject. McCartney was later dismayed to discover that, rather than the ingenious declarations he recalled, his realisations amounted to the phrase "There are seven levels." Photographer Robert Whitaker based his photo "Birdcage" on the song's lyrics. The photo shows George Harrison's head and shoulders inside a birdcage with the cage door open. The cage was among the props assembled by Whitaker for the 25 March 1966 shoot that produced another photo – featuring the Beatles in butchers' coats and
