Lady Gaga’s ‘Sound of Music’ Oscars tribute: The highlight of the night?

Lady Gaga just earned a Grammy for her duet album with Tony Bennett, but it turns out her appearance at this year's Oscars might've been a bigger triumph. 

The pop star performed a tribute to “The Sound of Music” that earned raves from Julie Andrews and the audience at the Kodak. The medley was tasteful, versatile, and perfectly sung.
