TONIGHT'S MUST-SEE

"American Idol," 7 p.m., Fox. Here is "Idol Gives Back," an epic show in intent — raising millions for poor kids in Africa and in the U.S. — and in production. Producer Ken Warwick promises he'll keep it fun. The list of singers is huge and subject to change. There are past champions Kelly Clarkson and Carrie Underwood. And performers from earlier this year, Gwen Stefani and Michael Buble. There are Celine Dion, Pink, Josh Groban and Annie Lennox. Groups include Il Divo (the supergroup created by Simon Cowell) and Rascal Flatts. Sacha Baron Cohen will be there in his Borat character; Warwick says, we can expect that part to be funny. And, tentatively, there will be appearances — funny or serious — by Hugh Grant, Forest Whitaker, Keira Knightley, "Harry Potter's" Daniel Radcliffe, Rowan Atkinson, Brad Garrett and Teri Hatcher.

OF NOTE

"Jericho," 7 p.m., CBS. War could erupt between towns: New Bern sends armed people to get salt from Jericho's mine.

"According to Jim," 7 p.m., ABC. Andy wants to sell the grill that his brother-in-law Jim gave him years ago. That sets off a disagreement.

"Notes From the Underbelly," 7:30 p.m., ABC. Complications of pregnancy: Lauren's sex drive has diminished and her breasts have expanded, seemingly increasing the desire of her husband — and her students.

"Lost," 8 and 9 p.m., ABC. First is a rerun of last week's episode; Desmond has another of his flashes into the future, then leads a journey into the jungle. Then comes a new episode in which Juliet, the fertility expert, discerns who is the father of Sun's unborn baby. Also, ABC says, Desmond allows a foe to help save a mysterious new inhabitant.

"Crossing Jordan," 8 p.m., NBC. Macy reluctantly says Jordan can return to work, if she takes it easy; instead, she plunges into a murder case. Woody has another murder and Bug seems altered by his encounter with Homeland Security.

"Bill Moyers Journal," 9 p.m., PBS. Moyers returns to weekly TV, resurrecting a show title he first used 35 years ago. The opener, focusing on news coverage of the Iraq war, gets a Wednesday spot. Afterward, "Journal" will be consigned to Fridays, a night when many stations skip the network shows.

"Medium," 9 p.m., NBC. Allison keeps dreaming of waking up in the snow. Meanwhile, her husband returns to his office for the first time since the shooting.
