For the folkloric record, here are links to a political song/chant that I've just come across:

Barack Obama supporters at a Sarah Palin fundraiser {Pittsburgh, Pennsylvania}


Here are the words that I transcribed from the video Mama Mama...Obama video

{The video starts with the male soloist saying "Hold your head up head". However, the soloist doesn't complete that verse but appears to start the song again. The song uses a call & response pattern, with the group repeating word for word what the soloist says}.

Mama Mama....Obama

{A soloist sings the first line}
Mama Mama can't you see. {group repeats="gr"}
What Obama done for me. {"gr"}
Mama Mama can't you see. {"gr"}
What Barack has done for me. {"gr"}

Standin tall and lookin good {"gr"}
He* oughta be in Hollywood {"gr"}
Standin tall and looking good {"gr"}
He* oughta be in Hollywood {gr"}

Chorus:
Oh-Oh-Oh-Oh {"gr"}
Oh Oh-Oh-Oh-o-Oh {"gr"}

Ain't no sense in lookin down. {"gr"}
Barack Obama's comin to town. {"gr"}
Ain't no sense in lookin down. {"gr"}
Barack Obama's comin to town. {"gr"}

*Some of the group sung "we".

Note: The video shows that some of the protestors who were singing held SEIU union signs. Also, fwiw, the majority of the protestors appeared to be White women and White men.

"Mama Mama Can't You See" is a call & response song that is based on the African American spiritual "Honey In The Rock". This song has also been used as a military cadence {jodie} and as a children's handclap rhyme.
