It's been revealed that Super Junior's Kyuhyun was almost unable to participate in a recent recording of KBS2TV's  'Immortal Song 2' due to his poor health condition. Kyuhyun recently joined the program and had a successful first round performance on July 25th. He was scheduled to participate in the second round on August 1st, however, due to his overladen schedule with preparations for 'Immortal Song 2' and Super Junior's comeback, Kyuhyun's health had declined. During the rehearsals for the second round, Kyuhyun's voice would barely come out and he continued to have trouble during the dry rehearsal. Later, the camera rehearsal was put to a halt because we was unable to sing. 'Immortal Song 2''s PD Kwon Jae Young said,

"Kyuhyun's condition was so bad that we were unable to film. After stopping the camera rehearsal, Kyuhyun went to the hospital and his condition improved after receiving emergency treatment. Luckily, he was able to show a successful performance on the actual show. Though he was not in the best condition, his performance was not inferior compared to the other singers on the show."
