The rapper behind the record breaking viral hit Gangnam Style has apologised for previous concerts which featured anti-American lyrics.
As he prepared for a performance to be attended by US President Barack Obama and his family, Psy issued the apology as reports surfaced in the US about two performances 2004 which were critical of the US military.
– Rapper and pop singer Psy statement
While I'm grateful for the freedom to express one's self, I've learned there are limits to what language is appropriate and I'm deeply sorry for how these lyrics could be interpreted
I will forever be sorry for any pain I have caused by those words
In one performance, which Psy said was from eight years ago, the rapper protested the deaths of two teenage South Korean girls who were run over by a US tank stationed in the country.
