"Rapp will appear at Civic on Sunday, June 11, at 4:30 p.m., after the matinee performance of Tick, Tick... Boom! He will read from his new book Without You: A Memoir of Love, Loss, and the Musical 'Rent,' sign autographs, sing, and answer questions from the audience."
I don't think Anthony is performing in TTB, he's just doing a book signing afterwards.
I recognize the addiction to being alive.
