Do you remember the power vocal group V.O.S? Well, it's been three years since they last made an appearance on stage, but the wait is over! While the group is not returning with a new album as of yet, they will be taking part in KBS' 'Immortal Song' to show off their amazing singing talents.

On the 21st, V.O.S appeared at the filming location of 'Immortal Song' and revealed before recording for the show, "We're really nervous. It's an unfamiliar feeling." They then proceeded to passionately sing their rendition of Shin Seung Hoon's "You are Just At a Higher Place than Me".

Choi Hyun Joon said, "I'm very nervous... The situation is awkward. I definitely feel the long hiatus... As it's a song I enjoy, there's a part of me that's more careful with it. It feels more burdensome than a new song... We made an arrangement using the original song as its center."

Kim Kyung Rok said, "I feel half expectant and half strange. I think I'm going to be very nervous on this stage... As it's been three years since we've greeted an audience on such a big stage as 'Immortal Song', I am worried I might make a mistake."

After their performance, the two of them said, "We're greeting you after a very long time away... We were lucky enough to get a chance to stand on stage for 'Immortal Song', and we ask for a lot of support."
