It is what it says it is: a full screening of 1965's musical classic The Sound of Music—featuring nuns and Nazis, bitchy baronesses and lonely goatherds, adorable Julie Andrews and swoon-worthy Christopher Plummer—where the audience is actively encouraged to sing along. To help facilitate the group-sing, each song's lyrics are featured onscreen as subtitles. Warning: The screening is preceded by a 20-minute "interactive screenings for dummies" mini-lecture that you should stay in the lobby and drink through. (5th Avenue Theatre, 1308 Fifth Ave, 7 pm, $18–$25.)
