POP/ROCK - Sept. 23, 1987

U2’s Bono Hewson went down in concert over the weekend, but the Irish band’s lead singer isn’t out. Hewson sprained his shoulder before a capacity crowd at Washington’s RFK Stadium, a hospital spokeswoman said. Hewson hurt himself when he slipped on a wet stage, ending the concert three songs shorter than usual. The singer--whose picture graces this week’s cover of “Rolling Stone” magazine--was admitted to Washington Hospital Center at 11:32 p.m. Sunday night, treated and released half an hour later.
