Watch Beyonce's Amazing Whitney Houston Cover

Over the weekend, some lucky people got to witness something extraordinary — a surprise Beyonce appearance, made at an event for Blue Ivy’s elementary school. According to Us Weekly, the L.A. performance was given to raise money for the Center for Early Education's 75th Anniversary Gala, and in addition to a few of the singer's go-to songs ("Crazy in Love," "Halo," "XO"), Bey also sang an incredible cover of Whitney Houston’s "I Will Always Love You," with a cadre of backup dancers in tow. Could you imagine how insane that must have been to witness?

Well, you don't have to — there's video to back it up, as you can see below. And, as you'll see, Beyonce clearly knows her way around the Houston classic — and cover songs in general. The list of her greatest covers spans the decades from '20s jazz classics to remixes of her own work. Of course, the most memorable Beyonce cover in recent memory isn't even of another performer's song. The 34-year-old completely revamped her 2003 tune "Crazy in Love," a staple in the singer's touring repertoire, for last year's Fifty Shades of Grey soundtrack, proving that no one in the world can do Beyonce better than Beyonce can do Beyonce.

Here are some of her other memorable covers.

1. Whitney Houston's "I Will Alway Love You"/"Halo" Mash-Up

Beyonce also sang the mash-up at Los Angeles' Staples Center in 2013 during a performance dedicated to Paul Walker.

2. Etta James' "I'd Rather Go Blind"

Bey began covering James classics like "All I Could Do Was Cry" following her portrayal of the jazz legend in 2008's Cadillac Records.

3. Etta James' "At Last"

Of course, who could forget this epic performance from Obama's inauguration?

4. Marilyn Monroe's "Diamonds Are A Girl's Best Friend"

This early Armani Emporio ad was one of Bey's first big solo endorsements.

5. Peggy Lee's "Fever"

The cover was a standout; the film for which she covered it, 2003's The Fighting Temptations, unfortunately was not.

6. Amy Winehouse's "Back to Black," With Andre 3000

The Great Gatsby soundtrack, which Beyonce's husband Jay Z produced, was filled with hits.

7. Queen's "We Will Rock You," With Britney Spears And Pink

The 2004 Pepsi campaign was among the company's most memorable Super Bowl commercials ever.

8. Luther Vandross' "So Amazing," With Stevie Wonder

This is from a 2005 all-star tribute to the "Never Too Much" singer.

No one slays a cover song like Bey does, that's for sure.
