If you watched Music Bank earlier today and especially 2PM's peformance of Without U, you would have noticed that Wooyoung was lipsyncing during his parts. This isn't surprising if you had remembered that Wooyoung had been showing signs of vocal cord nodule just before their comeback. A JYPE representative said after the show, "Since making a comeback with 2PM, Wooyoung's condition hasn't been at its best. Doctors have recommended that Wooyoung should not strain his vocals during this period and thus we decided to use the AR version for his part during the performance as a precaution." Wooyoung will however continue with his MC duties on Win Win and Inkigayo. 2PM has not been performing at 100% since making their return, as fellow member Junsu recently injured his knee and is now wearing a foot cast during performances, while hobbling around with a crutch for support. But despite the above, 2PM has had a pretty successful comeback, having already won a triple crown on M! Countdown while winning the K-Chart for two consecutive weeks. They will be looking to win their first Mutizen this Sunday on Inkigayo.
