U2 almost got sick of 'With or Without You' before Bono helped rescue the slow-building song from the trash heap. It became the band's first No. 1 U.S. hit.
After hearing the plight of the Mothers of the Disappeared (those who lost children to brutal regimes), Bono began to write the final song on 'The Joshua Tree.'
Both in scope and approach, U2's 'Red Hill Mining Town' was very much in keeping with the old American protest tunes which Bono had been delving into back then.
U2's propulsive song was inspired by Bono's visit to El Salvador in the midst of the country's civil war. He lashed out at the U.S.'s involvement in the lyrics.
