Apparently, Jacky Cheung songs are not his cup of tea :p
But his rendition of 秋意濃 at XG was great
Yesterday, he didn't appear in My Queen. According to the storyline, he shouldn't be appearing on Ep 18 as well. You could probably only see him on Ep 19 and 20.
Cross our fingers this Sunday that we could see him in the preview of Ep 19 :p
