U2 made their first US appearance on The Tomorrow Show, hosted by Tom Snyder, on June 4, 1981. They performed live I Will Follow and Twilight, the US accepted U2 instantly and their album, “Boy,” climbed the rock billboard charts. Their next album, “October” exhibited some growing pains but that didn’t last long. In 1983, U2 released “War” and then in 1984, they gave the world “The Unforgettable Fire,” both albums made U2 an 80’s phenomenon with nothing but sold out tours for the Irish rockers. After touring, U2 released their highest selling album in 1987, “The Joshua Tree,” and permanently etched a place for themselves as one of the biggest rock bands of all time.

They now had the freedom to experiment and that is exactly what they did with their next three albums, “Rattle and Hum,” “Achtung, Baby,” and “Zooropa.” “Zooropa” was followed by an enormous yearlong world tour that like prior tours, instantly sold out within minutes across the globe.

Among U2’s achievements is their undying devotion to humanitarian work in several underdeveloped countries. U2 has help support more than 15 non-profit organizations throughout their 35 year career, including Amnesty International, Greenpeace, African Well Fund and the Chernobyl Children’s Project, just to name a few.
