SINATRA: THE CLASSIC DUETS 8:30 p.m. Friday, Dec. 31 AETN (Comcast Ch. 3, Broadcast Ch. 2) Though Ol’ Blue Eyes has gone to that big nightclub in the sky, he left behind what mattered most about him: his voice. At turns haunting and playful, Frank Sinatra’s voice is one of the greats, and while Sinatra’s voice was good by itself, he really shone when paired with other great singers. To that end, we have this special, which collects footage of Sinatra singing with other legends of song and screen, including Elvis Presley, Ella Fitzgerald, Dean Martin, Peggy Lee, Bing Crosby and Sammy Davis Jr. Make it a double, baby, and enjoy. CONCERT MOVIE MARATHON Friday, Dec. 31 Turner Classic Movies (Comcast Ch. 30) 7 p.m. — ELVIS ON TOUR (1972) 9 p.m. — THE LAST WALTZ (1978) 11 p.m. — ABBA: THE MOVIE (1976) 12:45 a.m. — THE SONG REMAINS THE SAME (1976) 3:15 a.m. — ELVIS: THAT’S THE WAY IT IS (2001) Nothing says “New Year’s Eve” like a concert, especially with Dick Clark sidelined by a recent stroke. But with age comes responsibility, so believe us when we say we can’t remember the last time we saw a musical act on stage that didn’t include “Itsy Bitsy Spider” in its set list. That doesn’t mean, however, that you can’t catch a concert from your couch. Here, Turner lets you slip in the back door to some of the greatest filmed concerts, including sets by the King, disco freaks ABBA and a classic behind-the-scenes look at Led Zeppelin. FRONTLINE: THE JESUS FACTOR 9 p.m. Tuesday, Jan. 4 AETN (Comcast Ch. 3, Broadcast Ch. 2) While much hay was made in the aftermath of Election 2004 over the “Jesus Vote,” it remains to be seen how much a factor religion actually was in deciding winners and losers (we tend to think it had more to do with gays than with God). Whatever it was, one man who surely benefited from it was George W. Bush. Pushing the fact that he is a Christian at every opportunity, W. has positioned himself as both a political and moral leader, one who supposedly prays before every decision and is definitely Commander in Chief of the Christian Soldier brigades. Here, “Frontline” explores W’s faith, trying to figure out if Bush is as godly as he says he is, or simply a politician who knows how to push the electorate’s buttons.
