Frankie Laine, he was singing Jezebel
I pinned an Iron Cross to my lapel
I walked up to the tallest and the blondest girl
I said, "Look, you don't know me now but very soon you will
So won't you let me see"
The Iron Cross  was a military decoration in the Kingdom of Prussia, and later in Germany from 1817 till 1945. The Nazis added a swastika in the center of the cross.
