It used to be difficult to find some of the English covers they did on the show due to copyright but I've come across a few recently and thought I'd share my favourites/popular ones. The vocals and arrangements of the live instruments are always so good on this show as you can probably guess from the names the show gets.
Look forward to them being able to go outside of SK again. Was always good fun seeing the reactions of European's that don't know who they are when they start belting out some of the songs.
Will start with best vocalist in Korea and probably my favourite cover. Sohyang covering I Won't Give Up
Henry and another vocal legend in Lena Park covering Shallow
Sohyang and Seung-hwan covering My Heart Will Go On
Lee Hi and Henry covering Senorita
Fix You with Kim Feel and some others
Suhyun (AKMU) and Henry dueting Perfect
Both of them again covering Korea's favourite 2002
Crush and Henry covering Love Never Felt So Good (2nd half)
Henry covering There's Nothing Holding Me Back with Suhyun and Lena Park
Not an English song per se but Henry and Lena Park covering his OST It's You is my 2nd favourite cover from the show
They honestly put out so much good music on it.
