This is the best video I could find of the United States Coast Guard song, with lyrics. I will try to find out some information about the song and post it at a later date. I also know their is a longer version of the song, but I have not been able to find one with the complete lyrics being sung.
So here's the Coast Guard battle song, We fight on land or sea. Through howling gale and shot and shell, To win our victory. "Semper Paratus" is our guide, Our pledge, our motto too. We're "Always Ready" do or die! Aye! Coast Guard we are for you!
