Rockband Royal Pirates member Moon joined Jung Joon Young's radio show aired through MBC FM.

On July 11, Royal Pirates' agency stated: "Moon will be the permanent guest on the Wednesday corner of Jung Joon Young's radio show, meeting fans on a regular basis."

Moon, who made his first radio show appearance on July 11, awed listeners with his soft mid-low voice and wit.

On this day, Moon rearranged Um Jung Hwa's "Poison" in an acoustic version, performing the song live.

When asked why he chose "Poison," Moon stated that he personally knew Um Jung Hwa: "The Royal Pirates went to a karaoke with Um Jung Hwa in LA once, and we sang 'Poison' in front of her."

Moon, who also makes an appearance on SBS show program "The Rules of the City in New York" stated: "I love people and dogs, but the show makes me seem like I love girls only. I can't wait to show all the different sides of me."

Meanwhile, Jung Joon Young's radio program is aired every midnight.
