Bruno Mars Covers Adele's "All I Ask" With a Show-Stopping Finale

The "24K Magic" crooner performed the track he co-wrote with the British songstress

All Bruno Mars asks is: hand over the mic. 

The Grammy-winning crooner took the stage at BBC Radio's 1 Live Lounge Wednesday to perform a song he co-wrote with Adele, Philip Lawrence and Christopher Brody Brown called "All I Ask." The piano ballad, off the British songstress' third studio album 25, is a melancholy melody packed with heartbreak. 

While Adele has performed the track live on several grand occasions, including on Ellen DeGeneres' daytime talk show in February and at the 2016 Grammy Awards, it was Mars' turn to give the track a try. 

Backed by a full band and two harmonizing singers, the "24K Magic" star gave the song a dash of his signature cool with an electronic sound. For the grand finale, he riffed impressively through a few key changes before landing on the final note. "We love you, Adele!" he shouted before pushing over his stand for a necessary mic drop. 

He particularly loves singing the line "Take me by the hand while we do what lovers do," but it wasn't always that way. 

"We were aiming for that big, diva, ballad thing—that's what I envisioned," Mars told Rolling Stone. "But 'lovers'? I don't know if anybody really says 'lovers.' 'Yeah, we're lovers.' 'This is my lover.' I was like, 'Should we rethink that?'"

"But [Adele] was so gangster about it," he recalled to the magazine. "She was like, 'Nope. That's what it has to be.' And she was right. It's this grand word that makes the song bigger because no one says it. Because nobody talks like that, it pops out. It's not 'what boyfriends-and-girlfriends do'—it's this over-the-top 'lovers.' Sometimes I play it on the piano, and I look forward to singing that part. It's f--king perfect."
