Courtney Love Rules The Airwaves In This Week's 'Late Night Lineup'

For many late night fans, the countdown is on until the debut of Conan O'Brien's new show, which is set to appear on cable station TBS at 11 p.m. some time this fall. When the still-untitled show debuts, you'll really see some fireworks and one-upsmanship not only between O'Brien and former rival Jay Leno but also between O'Brien and David Letterman, Jimmy Kimmel, Jon Stewart and Stephen Colbert as they all struggle for late night dominance. But before those fireworks start blazing, we still have plenty of comedy, music and interviews to enjoy during the time when we should be climbing into bed, and this week offers up a bevy of excellent diversions from slumber.

Letterman has a particularly explosive week ahead of him, as he'll talk to recent "American Idol" reject Tim Urban on Monday (April 26) and will welcome the always-unpredictable Courtney Love for an interview and performance on Tuesday (April 27). The rest of the week is just as packed, with OK Go stopping by on Wednesday (April 28), the cast of "American Idiot" performing on Thursday (April 29) and the always-rocking Hold Steady on Friday (April 30). That is one loud week of late night rock.

Leno counters with a quieter but more eclectic batch of musical guests, featuring Melissa Etheridge on Monday and Laura Bell Bundy on Thursday. He'll also chat with Jessica Simpson on Tuesday and California governor Arnold Schwarzenegger on Thursday. Across town, Kimmel will turn the amps on for Dr. Dog (Wednesday) and another visit from Courtney Love and Hole (Thursday).

In the extra-late hour, Jimmy Fallon will welcome the likes of Gogol Bordello (Monday), Sharon Jones and the Dap Kings (Wednesday) and Paramore (Thursday) during another music-centric week for him. Meanwhile, "The Colbert Report" has been inching farther into awesome music territory (they had Gorillaz on last week) with visits from Sharon Jones and OK Go on Monday and Thursday, respectively.

The daytime shows don't offer as much in music this week, though Courtney Love will be on Wednesday's edition of "The View," which should be a good time. And be sure to tune in to "Ellen" on Wednesday for a sit-down and performance with Shakira.
