] The two brothers who created the fantastic "This Land"

] the current state of American democracy to the tune of
] "This Land is Your Land" -- have been threatened with a

I like what Guthrie had to say about it:

] "This song is Copyrighted in U.S., under Seal of Copyright
] # 154085, for a period of 28 years, and anybody caught
] singin it without our permission, will be mighty good
] friends of ourn, cause we don't give a dern. Publish it.
] Write it. Sing it. Swing to it. Yodel it. We wrote it, that's
] all we wanted to do."

Could that be construed as explicit licensing, a la Creative Commons?
