Happy birthday, Julie Andrews! The Oscar-winning singer and actress turns 81 on Oct. 1, 2016.

Andrews won an Academy Award for Best Actress for her breakthrough role in 1964's Mary Poppins, and she went on to win a Golden Globe for her performance in 1965's classic The Sound of Music.

She has appeared in dozens of other movies and TV shows over the years, including Thoroughly Modern MillieVictor/Victoria and The Princess Diaries.

This fall, Andrews' career is making something of a full circle. She's directing a new stage production of My Fair Lady, which opened September 6 at the Sydney Opera House. Andrews starred as Eliza Doolittle in the original hit Broadway production of My Fair Lady in 1956.

In honor of Andrews's birthday, here are some clips of her singing that will bring back the memories, including classic performances from Mary Poppins and The Sound of Music and a lesser-known clip of Andrews singing an operatic aria at age 12!
