Super Junior's Ryeowook teamed up with MONSTA X' Jooheon on the January 23 installment of 'Immortal Song'.

For the Kim Kwang Suk special of the show, Ryeowook covered the legendary artist's song "My Song". As one of the vocals of Super Junior, Ryeowook didn't disappoint as the third performer up, and with the help of Jooheon, put on an amazing stage.

It was (highlight for spoiler) who took the final win.
