Lost Lost

9/8c ABC
In the beginning, Jack took charge of the Oceanic survivors. And as "The End" begins, he's back in command — anointed by Jacob as the island's guardian and its protector from the Locke Monster, who now says he wants to destroy it. Where would that leave Ben, who seems to want to stay? Where's the island Desmond?  How (and will) the L.A. and island stories merge? More questions? We each have 815, at least. Maybe we can thrash them out at a diner after tonight's concert. We understand that Drive Shaft is playing. — Paul Droesch

Brooks & Dunn: The Last Rodeo
8/7c CBS
Kix Brooks and Ronnie Dunn, the most successful duo in country-music history, are calling it a career (at least as a duo) after 20 years of chart-topping hits that began with their 1991 smash "Brand New Man." Int his special, the two are lauded by their peers in a high-energy tribute concert that includes such country luminaries as Kenny Chesney, Lady Antebellum, Tim McGraw, Reba McEntire, Brad Paisley, George Strait, Sugarland, Taylor Swift, Carrie Underwood and Keith Urban. The pair will also be awarded the Academy of Country Music's Milestone Award in recognition of their stellar career and for the most wins of any artist in ACM's history. — Tim Holland

Celebrity Apprentice
9/8c NBC
It's strictly business when Donald Trump's reality competition show closes Season 9 with the conclusion of the two-part finale. It's tea for two when the final celebrity duo — actress Holly Robinson Peete and bandanna-clad rocker Bret Michaels — continue working on their new tea product before launching it. The contest crescendos when the Donald then names the winner live from the Skirball Center in New York City. Heightening the drama is Michaels' recent health scare: He's currently rehabilitating from a brain hemorrhage he suffered in April. He's expected to make a full recovery, and he's reportedly hoping to be on hand tonight. — Dean Maurer

Family Guy
9/8c Fox
Three years ago, Family Guy did a season-opening hour-long Star Wars send-up. Folks liked it (and the DVD sold well), so those galactic Griffins are at it again, closing a season this time with an Empire Strikes Back spoof. Once again, Chris doubles as Luke Skywalker, Peter as Han Solo, Lois as Princess Leia, and Stewie as Darth Vader. Other villains include the Cookie Monster, while James Caan and John Bunnell (World's Wildest Police Videos) have voice cameos as themselves. — Paul Droesch

The Simpsons
8/7c Fox
Fox's long-running iconic cartoon meets the network's perennial ratings juggernaut as Matt Groening's deliciously subversive satire wraps up its 21st season with a nod to American Idol. Moe the bartender discovers a previously unknown talent for judging contests and gets a chance to join the panel of judges on the pop-stardom launching pad. Simon Cowell, Ellen DeGeneres, Kara DioGuardi, Randy Jackson and the ubiquitous Ryan Seacrest have voice cameos as themselves. — Fred Mitchell

MLB Baseball
8/7c ESPN
Baseball's premier interleague rivals cap off their first series of the season as the Yankees hop the No. 7 train to Queens to meet the Mets. The Bronx Bombers made themselves right at home at Citi Field last year, outscoring Jerry Manuel's beleaguered bunch 18-3 in a three-game sweep that saw the Mets combine for as many hits (nine) in three days as the Yanks' part-time duo of Brett Gardner and Ramiro Pena. A matchup of Big Apple aces CC Sabathia and Johan Santana is scheduled, which may just mean a fast-paced affair that allows both teams to catch the final moments of Lost in the clubhouse. — Roger Leister

Seven Deadly Sins
8/7c Lifetime Movie Network
Popularity comes with a price as depicted in this 2010 four-hour miniseries based on Robin Wasserman's Seven Deadly Sins novels. In Part 1, Harper Grace (Dreama Walker) is dethroned as the school's most popular girl by a new transfer student (Rachel Melvin) with shameless appeal. But Harper has bigger problems than losing favor with the students — she's accused of murder. As the sheriff tries to solve the case, the town's many secrets come to light. The miniseries, which concludes tomorrow, also stars Eric Close. — Rhoda Charles
