South Korean President serenades guests with 'American Pie' at White House state dinner.

South Korean President Yoon Suk Yeol surprised guests at the White House state dinner by singing "American Pie," his favorite song, after a musical medley by Broadway stars. President Joe Biden praised Yoon's musical abilities and gifted him an autographed guitar from Don McLean. The performance came after the two leaders announced an agreement to counter North Korea's nuclear threats. Yoon is on a six-day state visit to the US, which marks the 70th anniversary of the alliance between the two countries.
