"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 ours, cause we don't give a darn. Publish it. Write it. Sing it. Swing to it. Yodel it. We wrote it, that's all we wanted to do."
