A reader sent over this “special guest” briefing memo from Rep. Charlie Rangel’s office that is being sent to attendees who have confirmed their plans to attend the embattled Harlem congressman’s birthday fundraiser this evening at the Plaza Hotel in Manhattan.

Note that both Sen. Chuck Schumer and AG Andrew Cuomo are expected to speak. Neither Democrat has yet publicly confirmed – either in person or through aides – that he plans to be on hand for this event, which Rangel has been promoting the daylights out of via robocalls, Tweets, traditional snail mail and YouTube.

As recently as this morning, Schumer told YNN during a stop in Syracuse that he had to check with his office about his schedule for this evening. Cuomo’s office didn’t have a definitive answer when I called this morning.

Rep. Joe Crowley is to introduce the “master of ceremonies” Gov. David Paterson, who briefly wavered about sticking to his agreement to participate, but apparently is back on board. Other speakers include: Assembly Speaker Sheldon Silver, Mayor Bloomberg, Sen. Kirsten Gillibrand, and NYC Council Speaker Christine Quinn.

Paterson is, according to this memo, to acknowledge the presence of former NYC Mayor David Dinkins and his father, ex-state Secretary of State Basil Paterson. And then Rangel speaks. Dionne Warwick will take the stage after the congressman, and then do a “Happy Birthday” duet with Chuck Jackson.

And, there will be cake!
