If you had been speaking for 79 years, your message might grow stale to even yourself. Not so for the Tulsa Town Hall, even as it nears an eighth decade bringing enlightening discussions from engaging speakers to Tulsa. Writer Khaled Hosseini opens a new season of lectures with “Afghanistan Through the Decades: An Émigré’s Personal Perspective” at 10 a.m. Friday, Oct. 4, in Chapman Music Hall at the Tulsa Performing Arts Center, 101 E. Third St. The author of the best-selling novels The Kite Runner and A Thousand Splendid Suns will also be a special guest the night before at a Tulsa Reads author event (see calendar). Want more? Tulsa Town Hall has also booked journalist Dan Rather (Nov. 8), author-historian Timothy Egan (Feb. 7), actress Mia Farrow (March 14) and chief engineer of the Curiosity Mars rover missions, Gentry Lee (April 11). Subscriptions to the series are $75, available at www.tulsatownhall.com.
