U2 [SEP] Formation and early years (1976–1980)
The same day, U2 played a show at the 2,000-seat National Stadium in Dublin as part of an Irish tour. Despite their gamble of booking a concert in such a large venue, the move paid off. Bill Stewart, an A&R representative for Island Records, was in attendance and offered to sign them to the label. The following month, the band signed a four-year, four-album contract with Island, which included a £50,000 advance and £50,000 in tour support.
