Comedian Jung Jun Ha and talented vocal group Sweet Sorrow have united again as charity volunteers.

The comedian and the group have previously worked together back in June 2011 for the charity album for the 'Infinity Challenge' special, 'Seohae Ahn Highway Song Festival'. The five bonded while working on the charity album under the group name Sweet Cotsorrow. They released a song titled "Will You Give Me Affection".

It was belatedly revealed that Jung Jun Ha and Sweet Sorrow had volunteered at a welfare center that is�currently�situated at a farmhouse, which was abandoned 15 years ago.�Through social networking sites (SNS) and SBS's homepage, approximately 30 fans have joined to help re-build the center as well as spend quality time with the children.

SBS will be airing footage of their service on '2012 Hope TV' at 8:45PM KST on May 5th.
