Paul Revere rides again, but he's traded his horse for a Harley.

Obviously, this isn't the Revere from Boston who warned of approaching British troops. This is the modern-day revolutionary who challenged the British invasion on the American music charts of the 1960s.

Now, the intrepid leader of Paul Revere & The Raiders is off on another crusade, riding his motorcycle from Portland, Ore., to Washington, D.C., to promote the causes of military veterans. His "Ride to the Wall" will bring him to Bryan Harley-Davidson, Interstate 35 and 27th Street in Moore, from 4 to 6 p.m. today.

Revere and the Raiders are scheduled to headline a musical tribute to Vietnam veterans in Washington, D.C., on May 27.

Also appearing at that event will be Adrian Cronauer, the Armed Forces Radio disc jockey that inspired the film "Good Morning Vietnam," and Miss America 2000 Heather French Henry, whose father is a Vietnam War veteran. She is founder of Heather French's Foundation for Veterans.

Revere's cross-country journey and the Washington, D.C. show are functions of the Ride to the Wall Foundation, a nonprofit organization making funds available to various approved veterans' outreach programs, and Rolling Thunder Inc., which educates the public on prisoner-of-war and missing-in-action issues.

For the past 14 years, motorcyclists have joined Rolling Thunder in Washington, D.C., on Memorial Day Weekend to demonstrate for the full accounting of all POW/MIAs and veterans' issues, and to honor the men and women killed in action.

This year marks the 26th anniversary of the Vietnam War's end, and more than 400,000 people are expected to attend the ceremonies on the mall between the Washington Monument and the Lincoln Memorial.

In conjunction with the event, Paul Revere & the Raiders are also releasing a compact disc titled "Ride to the Wall" on Rhino Records, which features new recordings of classic rock tunes from the Vietnam era and three original songs written by Vietnam veterans.

Net proceeds from the sale of the disc will be donated to the Ride to the Wall Foundation. It is the first nationally-released material by the Raiders in two decades.

Revere became interested in veteran's causes a few years ago, when he added the old Animals hit "We Gotta Get Out of this Place" to the band's set list.

"We added it because it was written by Barry Mann and Cynthia Weil, who wrote 'Kicks' and 'Hungry' for us in the '60's," Revere said on the Ride to the Wall web site.

"It was perfect for us because it was one of their songs, it was similar to some of our hits, and it fit nicely in our show. What happened next was a surprise."

Veterans in the audience responded emotionally to the song and began approaching Revere in autograph lines.

"They'd...say, 'Thanks for doing all those great old songs, especially 'We Gotta Get Out of this Place.' Boy do I remember that from Vietnam. It was our theme song over there.

"After hearing that over and over from people in autograph lines, I started dedicating that song to the vets," Revere said.

Revere's ride also marks the 30th anniversary of his ride in 1971 to promote the Raiders' recording of "Indian Reservation," which sold 4 million copies.
