Often we hear of bands allowing fans to bootleg their shows, however this studio bootleg was not allowed and was considered to be the most talked about bootleg of U2’s career
In February 1991, U2 resumed the album’s sessions in the seaside manor “Elsinore” in Dalkey, renting the house for ₤10,000 per month. 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 the spaces. Within walking distance of Bono’s and The Edge’s homes, the sessions at Elsinore 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 conceived an alternate persona based on a pair of oversized black sunglasses that he wore to lighten the mood in the studio. Bono developed the character into a leather-clad egomaniac also called “The Fly”, and he assumed this alter ego for the band’s subsequent public appearances and live performances on the Zoo TV Tour.
