When American Idol went to the movies this week, contestant Quentin Alexander stole the show.

The New Orleans native stripped down Olivia Newton-John and John Travolta‘s “You’re the One That I Want” from Grease and wowed Thursday’s crowd despite never having seen the 1978 musical.

Even though the 21 year old did not get rave reviews from the judges, Jennifer Lopez did call his performance “haunting and beautiful.”

After the live show, Alexander told PEOPLE he found the Lo-Fang cover on Spotify: “I’d never seen Grease, so it was just a song to me. I connect really deeply with the way he has that message because he took the time to push out the lyrics, and, as an artist, I always want what I say and my feelings to come first.”

At the end of the two-hour show, there was one contestant to whom the judges were “Hopelessly Devoted”: Brooklyn’s Qaasim Middleton – Lopez, Keith Urban and Harry Connick Jr. unanimously opted to use the once-in-a-season save, meaning next week will feature a dreaded double elimination.

“I was just performing my heart out and letting them know that I have something to bring to this table that I feel really lights up,” Middleton told PEOPLE. “I really appreciate the opportunity to be here and hone my craft. It sucks to know that I got the lowest number of votes, but at the same time the judges have faith in me, and I’m really, really appreciative of that. Now I just have to show America what the judges see in me.”

American Idol airs Wednesdays (8 p.m. ET) on Fox.
