The office of Sen. Edward Kennedy (D-Mass.) announced Thursday afternoon that it would provide a live webcast of the late Senator’s memorial service being held Friday night at the John F. Kennedy Library in Boston.

The service, set to begin at 7 p.m., will feature eulogies by Vice President Joseph Biden and some of Kennedy’s closest colleagues, including Sens. Chris Dodd (D-Conn.), Orrin Hatch (R-Utah), John Kerry (D-Mass.) and John McCain (R-Ariz.). Kennedy’s nephew and former Rep. Joe Kennedy (D-Mass.), Massachusetts Gov. Deval Patrick (D) and Kennedy’s niece Caroline Kennedy are also scheduled to speak at the service, which is closed to the general public.

The live feed will be broadcast on a Web site set up by his family in the wake of Kennedy’s Tuesday night death. Kennedy, 77, died after a more-than-yearlong battle with brain cancer.

By noon Friday more than 33,000 visitors had viewed Kennedy’s casket, in which he lay in repose at the John F. Kennedy Library since Thursday night.

Meanwhile, organizers of Kennedy’s burial procession in Washington have expanded what initially was described as a brief “pass by— of the East Front of the Capitol into a broader prayer vigil. Kennedy’s motorcade is expected to reach the East Front on its way to Arlington National Cemetery at 4 p.m. Saturday, when a brief program of prayer and song is planned.

Current and former Kennedy staff as well as the public are expected to attend.
