said the vocal melody in the final version of the song differed from his original demo, but that otherwise most of the musical ideas from the demo were present in the completed song. The Edge achieved the guitar tones on the song using four pieces of equipment: a 1966 Fender Telecaster guitar, a Line 6 DM4 Distortion Modeler effects pedal, a Korg SDD-3000 digital delay pedal, and the Fender Deluxe amplifier. The distortion pedal is used for the raw sound of the main power chord riff, while the delay pedal is used for the clean, ambient accent notes in the song's instrumental break. Composition At the beginning of the song, Bono counts off in Spanish "Unos, dos, tres, catorce!" In English, this translates to "some, two, three, fourteen!" When asked about this oddity in an interview for Rolling Stone, Bono replied "there may have been some alcohol involved". The count off was parodied by novelty singer Richard Cheese on his version of U2's "Sunday Bloody Sunday" on his 2005 album Aperitif for Destruction. A Spanish reply of "¡Hola!" is also heard behind the "Hello, hello" of the refrain, as well as "¿Dónde está?" ("Where is it?" or "Where are you?" depending upon if this is intended as a question to the location of Vertigo or Bono himself) after the line "I'm at a place called Vertigo". The "Hello, hello" line itself is reminiscent of similar lyrics in the song "Stories for Boys" from U2's debut album Boy; in Vertigo Tour concerts, the band frequently included a section of the latter song in their performances of "Vertigo." Promotion U2 performed "Vertigo" in a television commercial for the Apple iPod as part of a cross-marketing plan to promote both the album and Apple's music products (especially the U2 Special Edition iPod and the iTunes Music Store's exclusive digital box set for U2, The Complete U2). Live performances U2 performed "Vertigo" at a number of promotional appearances in 2004 and early 2005, prior to the song's tour debut on the opening night of the Vertigo Tour. Since the first date of the Vertigo Tour, the band has virtually performed "Vertigo" at every single full tour concert, the only exceptions being the first few concerts of The Joshua Tree Tour 2017. On the Vertigo Tour during the North American arena legs as well as the 2006 stadium legs, "Vertigo" was typically the second song
