Meet Tu Ching Liang - the Taiwanese taxi driver who hosts karaoke contests inside his cab.
The 57-year-old driver offers his customers a discount if they sing karaoke - or even a cash prize if they're good enough. Liang then uploads the performances to YouTube - and also blares them from speakers mounted on the outside of the car.
Tu says his goal for customers is "To train them to be a superstar." His dream is to one day have Ed Sheeran as a passenger.
