THE BIG BANG THEORY: Leonard and Amy help Sheldon cope with the shame he's feeling after his accidental contribution to science is disproved. (Michael Yarish/Warner Bros. )

“Sound of Music Live!” (NBC at 8 p.m.) airs amid criticism from musical fans and Julie Andrews devotees. Carrie Underwood, who will play Maria, can’t exactly match Andrews because realistically no one can, but can she give the musical all it deserves? And more important, how is this live component really going to work? Will there be live sheep? How will she craft those curtain dresses in mere seconds? Expect rolling hills, lederhosen and an almost certain Twitter explosion.

The documentary “Comedy Warriors” (Showtime at 8) follows five severely wounded Iraq/Afghanistan veterans while they work with professional comedy writers and A-list comedians such as B.J. Novak, Bob Saget and Lewis Black to cope with their personal experiences through the healing power of humor. The soldiers write their own stand-up routines and find new perspectives from which to view their injuries and their lives.

Sheldon gets super sad when his accidental scientific discovery is disproved on “The Big Bang Theory” (CBS at 8). Amy and Leonard help him deal with his shame while Howard and Bernadette make the mistake of opening their home to Raj for a week.

RETURNING SHOW: The formidable Patti Stanger is back to finding love for those select few she deems worthy and ridiculing those she does not on the Season 7 opener of “The Millionaire Matchmaker” (Bravo at 9). Prepare for an influx of new, overly attractive assistants bubbling around Stanger and her new swanky Marina del Rey office. This week’s victims are actor Don Swayze and a hapless party planner.

SERIES PREMIERE: On the new show “Best Bars in America” (Esquire at 9), comedians Jay Larson and Sean Patton celebrate the 80th anniversary of Prohibition’s repeal with a tour of the nation’s best bars. (Sounds like another excuse to drink.)

SERIES PREMIERE: Courtney Kerr, who was the breakout star of Bravo’s “Most Eligible Dallas,” returns to the network with “Courtney Loves Dallas” (Bravo at 10). In typical Bravo form, the reality show finds her looking for love and exploring career opportunities with her exploding full-time fashion blog and all that.
