In February 1991, U2 moved the album's recording sessions to the seaside manor Elsinore in the Dublin suburb of Dalkey, renting the house for £10,000 per month. The band nicknamed the house "Dog Town" for the "tackiness" of its exterior dog kennels, and the location was credited as such in the album notes. Lanois' strategy to record in houses, mansions, or castles was something he believed brought atmosphere to the recordings. Dublin audio services company Big Bear Sound installed a recording studio in the house, with the recording room in a converted garage diagonally beneath the control room. Video cameras and TV monitors were used to monitor and communicate between the spaces. With Elsinore located within walking distance of Bono's and the Edge's homes, the sessions there were more relaxed and productive. The band struggled with one particular song—later released as the B-side "Lady With the Spinning Head"—but three separate tracks, "The Fly", "Ultraviolet (Light My Way)" and "Zoo Station", were derived from it. During the writing of "The Fly", Bono created a persona based on an oversized pair of black sunglasses that he wore to lighten the mood in the studio. The character, also named "The Fly", evolved into a leather-clad egomaniac meant to parody rock stardom. Bono assumed this alter ego for the band's subsequent public appearances and live performances on the Zoo TV Tour.
