The Red Flag
A socialist song, written by Jim Connell. (supposedly on a train journey between Charing Cross and New Cross). It is the anthem of the British Labour Party, and is usually sung at the end of their annual conference.
It temporarily fell out of favour when its sentiments didn't fit the image of Tony Blair's New Labour, and a parody of the traditional words appeared:
"New Labour's flag is palest pink
it's not as red as you might think,
and Tony's added shades of blue
he does not care for me and you".
