Next year, 2018, is the 100th anniversary of Leonard Bernstein’s birth. To honor him, we’re taking a look at the creation of "West Side Story," Bernstein’s most significant contribution to the world of Shakespeare. To help us out, we’ve invited in two guests with extensive knowledge. Mark Horowitz is archivist for the Leonard Bernstein Collection at the Library of Congress—nearly 400,000 items, including music manuscripts, letters, photographs, audio and video recordings, fan mail, and even some of the maestro’s old batons. Nigel Simeone has produced two books on Bernstein, "Leonard Bernstein: West Side Story" (2009) and "The Leonard Bernstein Letters" (2013). Nigel and Mark are interviewed by Neva Grant.
