Letters Live Thurs - Anyone know the lineup?

Hi everyone…I attended the first day of the last edition of Letters Live at the Town Hall when you at least knew that Benedict Cumberbatch would be there. This time I do not see any hints about who they got as readers. Does anyone have a bit of an inside scoop by any chance and can share a few likely names? I don’t live in the city and would love to get a sense of whether it is worth the money for me this time. Thanks in advance!
