Sunday Bloody Sunday (1983)

From the War album, "Sunday Bloody Sunday" is a powerhouse in the U2 canon, performed on every major tour since its debut. It's a classic U2 protest song about the troubles in Northern Ireland. Larry's militaristic drumming and Edge's abrasive guitar drive the song, while Bono's powerful lyrics cry out "How long, how long must we sing this song?"

The song, which reached number seven on Billboard's Mainstream Rock chart in the 1980s, has now become a global plea to end the violence that threatens the world today.
