"WaMu Presents MSG Concert Series." Iron Maiden headlines this concert at the Long Beach Arena in California. The 90-minute show was captured during the group's 1985 "World Slavery Tour." Throughout the MSG telecast, host Eddie Trunk will talk with Iron Maiden lead singer Bruce Dickinson.

8 (Fox) "The Moment of Truth." You can't watch this show without wondering what, besides money, got people to put themselves or loved ones through this trouble. They're asked personal, squirm-inducing questions, and their answers are compared to their reponses when hooked to a lie-detector machine.

9:30 (NY1) "On Stage." Walk down memory lane with New York 1's theater series, which marks its 10th anniversary with a half-hour special. The show will feature more than 40 clips of interviews with Broadway and Off-Broadway stars. Among those shown: Antonio Banderas, Alan Cumming and Idina Menzel.

10 (CBS) "48 Hours Mystery." In a step away from the show's usual murder-of-the-week format, the team looks into polygamy and the case of the Fundamentalist Church of Jesus Christ of Latter-day Saints. Show correspondents look into the secretive world of the FLDS.
