Thanks to aarv for uploading the original footage. Basically what happened was that in the summer 2006, Jackie Chan showed up as a guest singer in Jonathan Lee's concert. At that time Jackie was drunk and he showed disrespect to everyone at the concert, including the audiences, Mr.Lee and the piano player. Jackie scolded the piano player for not letting him saying 123 before playing the song. However, the piano player played the right tone for the song and he wasn't informed beforehand to wait for Jackie to count 123 and it was impolite for Jackie to scold the piano player for such a small case. The audiences kept telling Jackie to get off the stage but he didn't care and he acted like as if he owned the whole stage. What a loser...
