SEOUL (Reuters) - South Korean rapper Psy released his much-anticipated new single on Thursday hoping to repeat the success of “Gangnam Style” that made him the biggest star to emerge from the growing K-pop music scene.

The video for “Gangnam Style” has become the most watched item on YouTube with more than 1.5 billion hits and Psy’s horse-riding moves sparked an international dance craze. The details of his latest single, “Gentleman”, were kept under wraps until the song was released at midnight in New Zealand (1200 GMT).

The song, with a techno beat, was full of puns in Korean and contained the lines “I am a party mafia!” and the refrain, “I am a mother father gentleman”.

Psy, 35, will perform “Gentleman” in public for the first time on Saturday at a concert at Seoul’s World Cup stadium but he has been coy about what dance to expect this time, except to hint that it is based on traditional Korean moves.
