Someone told me since, the three vessel mentioned in the song
have been decommissioned and scrapped decades ago and I 
imagine there probably won't be a Russian invader anymore...

To prepare for defence they are keen
Sometimes it's the Lakes of Killarney

We'd fight like the devil all morning
Provided we're home by the night
