Today on PT, special music in honor of a few of our 44 Commanders-in-Chief. The inimitable James Earl Jones reads words by Abraham Lincoln, in Aaron Copland's "Lincoln Portrait." We'll tip our caps to Harry S. Truman, perhaps our most musical president. And hear how Ronald Reagan facilitated pianist Vladimir Feltsman's defection from the former Soviet Union. Plus works inspired by U.S. presidents, from George Washington to Bill Clinton.
