3. 'North and South of the River'
U2 wrote many great songs about the conflict in Northern Ireland, and one of their best came out shortly before the Belfast Good Friday Agreement brought peace to the region in 1998. The mournful and pleading "North and South of the River" was cut during the Pop sessions and released as a B-side to "Staring at the Sun." The only time they ever played it live was on a 1998 TV benefit for the victims of the Omagh bombing. They stripped the song completely down, and the result was absolutely beautiful.
