Not Going Out

It's been nearly two years since the second season of this amusing Britcom wrapped up on BBC America. When we last left off, Lucy left Guy after he proposed on their romantic getaway. Despite playing no small part in sabotaging that relationship, the always ambitionless Lee still has no real plan to address his feelings for the now-single Lucy in the Season 3 premiere. But she has some exciting news: She's pregnant. And that has Lee wondering if he could possibly be the father. — Karen Andzejewicz

Morgana worries that her witchy ways will lead to a date with a stake when, in a bid to finally snuff out sorcery, Uther brings in a legendary witchfinder (Charles Dance) to root out all magic men and women who call Camelot home. On the other hand, Merlin being Merlin means that he'll do what it takes to protect himself, Gaius and Morgana and hopefully avoid a char-broiled future. — Jeff Gemmill

Live From Abbey Road
8/7c Sundance
Studio performances by three diverse talents get the joint rockin' and poppin'. Must-see numbers feature Michael Bublé, who brings a Rat Pack swagger to the finger-snapping "Just Haven't Met You Yet," while Brit pop songstress Little Boots kicks it into high gear with the vibrant, electronica-infused "New in Town." Aussie rockers the Temper Trap, driven by the expressive, powerful vocals of lead singer Dougy Mandagi, rip through a bouncy "Fader." — Ray Stackhouse

NASCAR Hall of Fame Biography
11/10c Speed
Few names get NASCAR fans more emotional than that of Dale Earnhardt, a black hat early in his career before gradually building massive appeal for his aggressive racing style and throwback image, especially when the clean-cut Jeff Gordon arrived on the scene in the '90s. "The Intimidator" is the subject of the last of five profiles in SPEED's series on the inaugural class of inductees into the Hall of Fame in Charlotte. Earnhardt's tragic death at the 2001 Daytona 500 led to updated head-and-neck restraints and track barriers, while his car's No. 3 was retired (with the exception of a tribute by Dale Jr. this July 2). — Roger Leister
