Always one of the best and most inspiring TV specials of the year, the 2013 edition of the Kennedy Center Honors honors one actor (Shirley MacLaine), one opera singer (Martina Arroyo), and three popular musicians (Billy Joel, Carlos Santana and Herbie Hancock). Vintage performance clips and new tributes put their lives and works in context, and each year’s show leaves me feeling better about what TV can do when it really, really tries to aim high.
