Woman sings 979 songs and then collapses

SEOUL, Feb. 15 (UPI) -- A South Korean woman sang 979 songs and set an unofficial world record before collapsing of exhaustion.

Kim Seok-ok sang for 59 hours, 48 minutes, beating by 36 minutes the world record set last year by a German man, Yonhap said.

A Guinness Book of World Records observer was on hand, but had not yet declared Kim's record official. As Guinness rules allow, she rested 10 minutes each hour.

Before the event, Kim told local reporters she entered to encourage her husband, who has a brain tumor, Yonhap reported.
