A special opportunity to learn about the history of rock and roll from local radio expert, David McAlary, a veteran of 56 years in radio broadcasting, including several years as a disc jockey. He’ll talk about rock's roots, Golden Age, hits and even some forgotten records and fascinating facts, illustrated with visuals and soundtracks. McAlary retired from a 32-year news career with the Voice of America in 2007 and, as a student of 20th century American popular music, returned to his deejay roots to host a 1950s-’60s oldies show called Mickey Bo’s Rock ’n’ Roll Revue on the Internet at mickeybo.com. Sponsored by Connie Morella Library and Bethesda Metro Area Village. For security reasons, the library will lock the program 10 minutes after it begins, so be sure to sign in on time.
