McGraw, Rock and John highlight Harley concert

Harley-Davidson Inc. topped off its 100th birthday celebration in Milwaukee with a concert featuring country star Tim McGraw, rocker Kid Rock and pop star Elton John.

McGraw rode onto the stage Sunday on a Harley motorcycle and went straight into a set. Kid Rock later joined him in a song and did more songs with McGraw's band.

After McGraw completed the set, a large gospel choir filled the stage and sang as dozens of spotlights swirled their beams over the audience, forming a cone or wheel shape.

John later took his seat at the piano, getting a mixed reaction from the biker crowd.

Evelyn Hickey, of Austin, Texas, said she likes John but didn't think it was the best choice for the Harley event. She and her group were leaving after his first song rather than waiting for a closing fireworks show. "We all just are tired," she said. "It's been a long day."

The thousands of fans of the Milwaukee-based motorcycle maker spent Labor Day weekend taking in everything Harley — including motorcycle exhibits, memorabilia sales and a 10,000-motorcycle parade.

As the show began, fireworks shot from the sides of the stage. Blues Brother Dan Aykroyd welcomed the crowd and the Doobie Brothers opened the concert.

"We're a biker band. We believe that riding can set you free," said Pat Simmons, of the Doobies.
