Maybe symbolism is just symbolism, but the optimist in me says that Barack Obama's invitation to former Communist and life-long political activist Pete Seeger (along with Bruce Springstein and 89-year-old Pete's full-throated grandson Tao) to sing Woody Guthrie's anthem This Land is Your Land, and the fact that the once blacklisted folk legend chose to do not just the feel-good, approved-for-public-school-music-class-use verses, but all the verses, including Woody's long-censored "commie" verses, and that Obama was right there singing those verses along with the rest of the million people on the Mall, has to mean something.
