Taped at The John F. Kennedy Center for the Performing Arts on November 10, the 90-minute special features tributes and comic testimonials from a star-studded cast including Richard Belzer, Lewis Black, Margaret Cho, Ben E. King, Denis Leary, Bill Maher, Joan Rivers, Garry Shandling, Jon Stewart, and Lily Tomlin. George Carlin combined a once-in-a-lifetime voice, a face that could do anything, and be anyone, an understanding of language that William Safire (or William Shakespeare) would have tipped their hats to and was fearlessly funny. Before George passed away, he learned he was receiving the Twain and was genuinely pleased about it.
