An impressive crowd of superstars gathered to honor American veterans at the Concert for Valor in Washington, D.C. yesterday, including Bruce Springsteen, Foo Fighters frontman Dave Grohl and Zac Brown, who collaborated on a performance of the Creedence Clearwater Revival classic 'Fortunate Son.'

Both Grohl and Springsteen have performed the song repeatedly in the past, often with Creedence's John Fogerty joining in; a YouTube search yields multiple results for live Springsteen/Fogerty versions of the song, as well as Fogerty's team-ups with the Foo Fighters and Sound City Players. Clearly, it's a favorite song for each artist.

But as Consequence of Sound reports, not everyone was happy to hear it in the set list, with a handful of conservative pundits leading the charge against what they saw as an inappropriate performance of an anti-war anthem at an event held for military servicemen. Of course, "anti-war" doesn't necessarily mean "anti-veteran," and as CoS notes, Fogerty performed the song at a similarly themed White House event just last week. Odd as it might seem to some to hear singers decrying armed conflict at a concert honoring the troops, it stands to reason that the best way of keeping soldiers out of harm's way is to avoid sending them to war in the first place.

While political columnists argue, it's probably worth noting that the crowd seemed to enjoy the performance -- and you can check it out yourself in the fan-shot video above.
