Tony Award winner Bernstein, who made his debut with the Philharmonic-Symphony Orchestra of New York on Nov. 14, 1943, filled in to conduct when both Artur Rodzinski and Bruno Walter were unavailable. That concert joins more than 300 other recordings saved since the registry was established in 2000. The 25 new additions were selected for preservation because they are "culturally, historically, or aesthetically significant."

Other recordings added to the National Recording Registry include "Rapper's Delight" by the Sugarhill Gang; a 1977 concert given by the Grateful Dead at Cornell University; Bo Diddley's "Bo Diddley" and "I'm a Man"; the Booker T. & the M.G.'s single "Green Onions"; the 1967 album "Forever Changes" by the psychedelic rock band Love; the soundtrack album of "A Charlie Brown Christmas," performed by the Vince Guaraldi Trio; and "Purple Rain," the 1984 soundtrack album performed by Prince and the Revolution, among others.
