The one that stands out in my childhood is...

to the tune of Oh Taninbaum...

The workers flag, is deepest red,
It oft has cov'd our martyred dead
and ere thier limbs were stiff and cold
their blood has dyed its every fold
So raise the scarlet standard high
benieth its folds we'll live and die
though cowards cringe and trators sneer
we'll keep the red flag flying here!
