I checked a few sources to insure I was getting some good info, not just someone's personal opinion. Here's one link with the song, I'll Bet You're Sorry Now sung by someone whose name I did not catch.

Here are links to information about Tokyo Rose, Axis Sally ,Lord Haw Haw , and
Hanoi Hannah , and some more information about Tokyo Rose , all propaganda broadcast names from this and other wars.

Although there seems to be some disagreement about the exact details of how she ended up being used by the Japanese to broadcast psy-ops material to the American Forces in the Pacific, she was tried, convicted, and sentenced to ten years in prison, all of which she served. Later on Gerald Ford granted her a full pardon and offered the nation's apology for the prosecution.
