A New Year’s Eve concert to be hosted in D.C. by 30 Rock and SNL veteran comedian Tracy Morgan has been canceled, Live Nation spokesperson Robert Muller confirmed today. Tickets went on sale in October for the event, billed as the “New Year’s Eve Countdown with Tracy Morgan,” which was to have been held at the Warner Theatre. Live Nation promised more details on the cancellation later today, so we’ll be sure to update with any details on how ticket holders may get refunds, etc., when we know more.
