Strike

[Phil TK]

Now I wonder if you could tell me what is inoffensive about the following;

[size=1em]Hello, hello, we are the Billy boys,
Hello, hello, you'll know us by our noise,
We're up to our knees in Fenian blood,
Surrender or you'll die,
For we are the Brigton Derry boys.
[/size]

Dunno, you tell me.
That verse does however contain threats of violence which is a different thing altogether.
