The Academy Awards hailed the 50th anniversary of its all-time greatest musical Sunday, recruiting Lady Gaga to gracefully sing a medley of memorable tunes from "The Sound of Music."
Starring Julie Andrews and Christopher Plummer, the cinematic tale of the musical von Trapp family in Austria and their mischievous governess is a Hollywood classic.
In contrast to her own flamboyant concerts, Lady Gaga was all about the voice as she sang highlights from the beloved 1965 movie to the accompaniment of a string combo and a choir.
She then gave way to Andrews, 79, to announce the winner of the Oscar for best original score -- Alexandre Desplat, for "The Grand Budapest Hotel."
"Dear Lady Gaga, thank you for that wonderful tribute. Oh my god, it really warmed my heart," said the British-born thespian.
Looking back at the making of "The Sound of Music," Andrews said it was "really hard to believe" that a half-century had passed.
