This week is your last chance to see “Barber and Barberillo” at the Source, and it’s also a good time to get tickets for upcoming shows, including “Really Really” at Signature Theatre.

Last chance

The In Series’s Barber and Barberillo closes Sunday at the Source. The Post’s Charles Downey writes, “This kind of cute comedy, modest in production values and vocal quality, tries very hard to please. Its success will depend on the expectations of the listener.” 1835 14th St. NW. 202-204-7760.

The Sound of Music closes Sunday at Olney Theatre Center. The Post’s Nelson Pressley writes that the musical about a governess, seven mischievous children and their stern father is “capably delivered by Christopher Youstra’s small orchestra and [director-choreographer Mark] Waldrop’s winsome (and huge) cast.” 2001 Olney-Sandy Spring Rd., Olney. 301-924-3400.
