Watch: NCT's "Without You" Trio Displays Gorgeous Harmonies While Singing Medley Of Popular English Songs

More from “JaeIlYoung” please!

NCT 127 recently made a guest appearance on the February 8 broadcast of MBC Every1’s “Weekly Idol,” where they participated in some of the show’s classic corners, like dancing one of their songs at double the speed.

Later, members Taeil, Jaehyun, and Doyoung had a chance to shine when they sang a medley of Sam Smith’s “Lay Me Down” and Maroon 5’s “Sunday Morning,” while Taeil played guitar.

Often called “Without Yous” by their fans, in reference to their NCT U single together, the trio demonstrated how well their voices work well together as they harmonized, at least until the very end.

The MCs couldn’t help but poke fun at Doyoung when the ending sounded just the slightest off, and joked, “You can’t fool us when we have perfect pitch.” Jung Hyung Don and Defconn complimented Taeil, Jaehyun, and Doyoung on their skills, and added that they should form a sub-unit called “JaeIlYoung,” like Girls’ Generation’s TaeTiSeo.
