Singer�Wheesung is known for being able to pull off perfect live performances. Unfortunately, it's been revealed that his comeback stage on�Mnet's 'M! Countdown' will see him lip-sync his new song,�'They are Coming". Wheesung's representatives told SSTV that the star made a trip to the hospital yesterday for an acute gastric ulcer. The ulcer weakened his ability to deliver the results he was looking for, so it was decided that he would lip-sync instead. "Because he couldn't let go of his desire to sing live, he tried singing several times. However, because of the state of his health, he couldn't achieve a result that satisfied him... After negotiating with the production team, we decided to go ahead and record with an AR ('All Record': includes vocals + music accompaniment) instead of a MR ('Music Record': only includes the music accompaniment)." The recording was originally scheduled to include "They are Coming" and one more song off his recently released album. However, Wheesung was only able to record for "They are Coming" with the AR before having to make another trip to the hospital, where he was told that he needed to be admitted for a full week. His agency stated, "Wheesung is insisting that he will sing the other track [without lip-syncing]... We will have to see how his condition is after other groups finish recording, in order to decide whether to proceed with the recording [of the other track]." Make sure to check out Wheesung's comeback stage on 'M! Countdown' later today! Source + Photo: TV Report Tip:�supershingijjang
