ROGER WATERS PLAYS 'Dark Side,' unleashes giant 'Vote Obama' pig.

Rawstory:

Waters' biggest prop was an inflatable pig the size of a school bus that emerged while he played a version of "Pigs" from 1977's capitalism critique, "Animals."

The pig, which was led above the crowd from lines held on the ground, displayed the words "Don't be led to the slaughter" and a cartoon of Uncle Sam wielding two bloody cleavers. The other side read "Fear builds walls."

The underside of the pig simply read "Obama" with a checked ballot box alongside.
