Folk singer Arlo Guthrie, famous for his appearances at Woodstock and the movie “Alice's Restaurant,” is still at it. He’s about to launch a 50-city tour with a band that includes his own children.

At 62, Guthrie remains married to Jackie, his wife of 40 years. He lives on the 250-acre wooded spread in the Berkshires he purchased in 1969. And he continues to promote the ideals of the 60s generation – even as a registered Republican.

Guthrie is matter-of-fact about his political affiliation. "I've always been more comfortable being a loyal opposition than a 'Rah rah, let's go get 'em, we're in power now!' kind of guy,” he says.

Although he has some reservations about Sarah Palin, he admires her anti-elitist spunk. "I'm not suggesting that she would make a great VP or president, by the way, but what I am suggesting is that when we begin to limit who we think is in a position to do these things, we form ourselves naturally into the old sort of inherited positions, the ones that gave rise to the Kings and Queens of the world,” he says. “It disturbs me.”

Guthrie calls Woodstock a "single, unifying icon" – that's come to symbolize bigger, more important movements of the times, like the civil rights movement and the anti-war movement. Guthrie is, perhaps, better known for his anti-war anthem and film "Alice's Restaurant," than he is for Woodstock.

The “restaurant” of the famed movie is really a deconsecrated church. Guthrie bought it, and has turned into a spiritual community center. That said, Guthrie is still a child of the sixties – still vehemently anti-war and anti-establishment. They are beliefs born at Woodstock that have not changed with time.

“It revived your faith in human beings,” Guthrie explains. “It made you feel like you could trust your buddy, even though they were telling you that you couldn't.”

Anyone who saw Paul McCartney perform this summer saw in the audience moms, their kids, and their children's children – all singing along.

It's no surprise that a new survey found that the Beatles are truly a band that bridges generations. A Pew Research survey found the Fab-Four to be the top musical act across all generations. Michael Jackson is the number one pick for those under thirty.

People in the thirty to forty-nine age bracket selected the Eagles as their top choice. Baby Boomers, from 50-64, picked the Beatles. And those over 65 chose Old Blue Eyes, Frank Sinatra as their favorite.

And – 40 years after Woodstock Rock and Roll is the musical genre of choice for everyone under 65. Two-thirds of Americans say they listen to rock often or sometimes, with older people preferring country music.

Top 20 acts in the poll:

1. Beatles 2. Eagles 3. Johnny Cash 4. Michael Jackson 5. Elvis Presley 6. Rolling Stones
7. Aretha Franklin 8. Frank Sinatra 9. Carrie Underwood 10. Garth Brooks 11. Jimi Hendrix 12. Bruce Springsteen 13. Mariah Carey 14. Bob Dylan 15. Jefferson Airplane 16. Nirvana 17. Madonna 18. Coldplay 19. Kanye West 20. Grateful Dead
