When Jack Allison joined the Peace Corps in 1967, he never intended to write the number one hit song in Malawi or be described by Newsweek as more popular than Malawi's own president. A poor Southern white boy with a deep love of music, Jack only wanted an answer to one burning question: Should he become a minister or a doctor?

In the end, the answer Jack found was that he would choose medicine as a career. And, living in extreme circumstances in the world's then-poorest country, he would find even more-that he had the inner resources that allowed him to not only thrive but give the best of what he had to those who needed it the most.
