The citizens of China got an unusual greeting from Berkshire Hathaway billionaire Warren Buffett for the Lunar New Year: A video of him singing and playing the ukulele to the tune of “I’ve Been Working on the Railroad.”

The video was posted to YouTube by Russia Today. Buffett sang the classic American folk song before a model railroad kit last year at a charity event, the Wall Street Journal reports. It was supposed to be mixed with a greeting Buffett recorded as part of a five-hour gala television event celebrating the new year.

News spread earlier this month that he would be singing for millions of Chinese Internet users when the Chinese state media made a press anouncement. The Journal reported that Buffett asked the television to pull his greeting after he found out the show would include his previously recorded song.

Why he didn’t approve of the song is somewhat confusing. Buffett is no stranger to the stage: He’s played the ukulele solo and with the Quebe Sisters Band, and has even rocked out in a Geico commercial. In an interview with performance artists Roger Greenawalt and David Barratt, Buffett revealed the reason he learned the instrument: To impress a girl.
