On August 25 1987, Causing a Commotion was released as the second single from the soundtrack album Who’s That Girl, by Sire Records. Causing a Commotion was written and produced by Madonna and Stephen Bray, the song was inspired by Madonna’s relationship with then husband Sean Penn, and his abusive and violent nature.
On August 18 1987, Madonna performed the first of three sold-out Who’s That Girl Tour concerts at Wembley Stadium in London.
In total, Madonna performed for 216,000 fans during the three nights at Wembley.
On August 15 1987, Madonna opened the European leg of the Who’s That Girl World Tour 1987 at Roundhay Park in Leeds, England. Madonna performed for 73,000 fans during the show.
The title Who’s That Girl Tour came to Madonna during rehearsals when she looked at a gigantic image of herself, projected on a screen on the stage. She commented,
“Oh god, what have I done? What have I created? Is that me, or is this me, this small person standing down here on the stage? That’s why I call the tour ‘Who’s That Girl?’; because I play a lot of characters, and every time I do a video or a song, people go, ‘Oh, that’s what she’s like.’ And I’m not like any of them. I’m all of them. I’m none of them. You know what I mean.?”
On August 11 1987, Madonna’s True Blue album was certified 5x platinum (for shipment of 5 million units) in the USA.
Stephen Thomas Erlewine noted that “True Blue is the album where Madonna truly became ‘Madonna the Superstar’—the endlessly ambitious, fearlessly provocative entertainer that knew how to outrage, spark debates, get good reviews—and make good music while she’s at it.”
