You might even know it nearly killed her:
On her USO flight to Europe in February of 1943, her plane crashed in the Tagus River outside Portugal. One of the few passengers to survive, although severely injured, she was rescued by the co-pilot of the plane...She was back touring nearly as soon as she was up on crutches, despite having nearly lost her right leg; she had numerous operations on it and eventually recovered function after years of surgery and rehabilitation. She never lost her voice and she never stopped singing. Pictures from the war years show her on crutches, in a lace-up leg brace, in various war zones, smiling.
Could she sing? Well... "The famous composer and producer, Billy Rose, when asked to name the top ten female singers, is reported to have replied, 'Jane Froman and nine others.'" That's Wikipedia, but it does come with a cite.
A lot of people talk; Jane Froman went and did. When bad fortune struck, she kept right on. Remember that the next time you're feeling pessimistic about humanity.
