William Shatner has put out the word inviting everyone to join him in celebrating the late Leonard Nimoy beginning at 12 PM EST / 9 AM PST. There are no specifics about what he plans to do other than the invitation.
Shatner has been unfairly (my opinion) blasted in the media and on social media for not being able to attend Nimoy's funeral. Shatner has a fundraising commitment in Florida last night that would make his getting back to Los Angeles in time for the funeral very difficult if not impossible. His daughters are attending the funeral.
If you are not following him already, you can find Shatner on twitter here.
