The music groups TVXQ and Buzz and singer Kim Jong-kuk will give a benefit concert entitled `Voices For Children` on Dec. 3 at 6 p.m. at the Olympic Stadium in Seoul. They will donate all proceeds from the concert to the St. Severance Hospital of Yonsei University to fund the operations of seven children suffering from heart diseases.

The concert is being co-organized by the online music site Muse and entertainment planning company Instars.

Buzz visited the hospital on Nov. 10 to encourage the sick children and their parents, and promised that the performers would do their best to bring them hope and joy.

Muse (http://www.muz.co.kr) will give away free tickets to the concert every day to 20 random winners who click on the `I Want To Go To The Concert` button on its Web site until Nov. 23.
