Old klezmer tunes saved from library in Ukraine

A century-old archive of klezmer tunes was retrieved by Ukrainian and Japanese graduate students from the Vernadsky National Library of Ukraine, brought to New York and is now being digitized and notated. These tunes - about 1,400 of them - enlarge the klezmer repertoire four-fold. They haven't been heard in 100 years, and in the last couple of years have been recorded by klezmer artists from around the world. Jon Kalish reports.
