•Wondering why Neil Diamond would do a network special in the ratings dog-days of summer, which is when CBS is airing Neil Diamond: Hot August Night/NYC (tonight, 8 ET/PT)? It might be because the airdate coincides with the release of Diamond's new DVD, shot at his New York concert. CBS gets a better hour than it might otherwise have, fans get to see Diamond, and Diamond gets a free hour-long commercial. Not a bad deal for August.

•Lost's Adewale Akinnuoye-Agbaje guests on Monk (USA, tonight, 9 ET/PT) as an African visitor whose hunt for his wife's hit-and-run killer draws Monk's attention. Let's hope the outing emphasizes the case and their grief-induced bond, rather than the kind of lazy jokes that have become the show's late-run trademark.

•It's All Elvis, All Day on TCM Sunday. You'll have to get up early or set a DVR for perennial favorite Viva Las Vegas (6 a.m. ET/3 PT), but prime-time offerings are an interestingly mixed bag: It Happened at the World's Fair (8 ET/5 PT), King Creole (10 ET/7 PT) and G.I. Blues (midnight ET/9 PT). And never mind what happened at the World's Fair: Whatever happened to World's Fairs?
