This video was made during English Day 2005 in Raffles Institution. It's always a hit with the viewers whenever I showed it during assembly talks and workshops. The feedback was always the same: the voices were distorted by the soundtrack.
Finally, I found the time to sit down and re-record a new audio track. I used a free software - Power Sound Editor - to record the voices, and used a simple modulation effect to make my voice sound like Darth Vader.
Here it is! Enjoy it!
