Washington - Six weeks and 6,000 miles after launching his "Ride To The Wall," Paul Revere and his Raiders delivered a rain-soaked concert Sunday in honor of America's Vietnam veterans.

Thousands of veterans, their supporters and curious tourists crowded around the makeshift stage between the reflecting pool and the Lincoln Memorial to hear political speeches and to hear the Raiders play Vietnam-era rock 'n' roll. The group performed on a stage decorated with the front end of a white Ford Mustang.

Most veterans arrived on motorcycles as part of the 14th annual Rolling Thunder parade that started at the Pentagon parking lot, crossed Memorial Bridge and wound its way around the National Mall.

Revere, 63, and his drummer, Omar Martinez, were at the head of the parade on their borrowed Harley-Davidsons. They rode the motorcycles across the country, hooking up with the rest of the band in 34 cities to promote the ride and their new "Ride to the Wall" CD.

The Rolling Thunder and the "Ride to the Wall" concert series are to remind Americans that more than 1,000 American soldiers are still missing in Vietnam. Album proceeds will be used to fund veterans' causes.
