The thing about We Shall Overcome is that it's easy to improvise new verses and apply old verses to meet the need of new situations, such as water cannons and tear gas.

You couldn't do that with Swimming to the Other Side - but I can imagine that it'll become the kind of song where everybody knows the chorus though few know the verses to singbthem. But that's fine, because it's a great chorus and contains the heart of the song, and you could keep on singing it as long as needed - or until the tear gas got to you.
