Why couldn't MBLAQ's Mir sleep for two weeks?

Though he's likely gone through hundreds of performances by now, MBLAQ's Mir said he lost two weeks of sleep over 'Immortal Song 2'.

During filming for the upcoming episode, Mir and Seungho expressed how nervous they were about competing on the show. Mir in particular spoke in gibberish when he answered questions. When an MC pointed out how he stumbled over his words, Mir explained, "It's because I was so nervous I haven't been able to sleep properly for the past 2 weeks."

The two MBLAQ members covered the song "Men Bother Women" by Moon Joo Ran, and the dance break they had in the middle impressed everyone, including Poppin' Hyun Joon.
