Darius Rucker used his vocal talents for a good cause once again this week. The charitable Charleston native raised $260,000 for the Medical University of South Carolina's Children's Hospital with a 90-minute concert of classic Frank Sinatra tunes. The sold-out 'Darius Rucker Big Band Show' included an orchestra backed by Peter Graves.

It was a real treat for the former Hootie and the Blowfish singer, who reportedly had the opportunity to sing 'The Lady Is a Tramp' with the Chairman of the Board himself at his 80th birthday celebration.

This isn't the first time that Darius has leaned on Old Blue Eyes for a good cause. The 'I Got Nothin'' singer did a similar shows in Charleston in 2004 and 2008, as well as in Florence, S.C., in 2006.

"I take this seriously. This is the real deal," Darius explained when promoting the 2008 performance (quote via The Post and Courier). "It's something I do for charities. I'm not trying to get a record deal. I love to do it if I can help a charity."

Darius is currently writing music for his third country album, slated for release later this year. In the meantime, he can be found on Lady Antebellum's Own the Night Tour. You can see Darius next in Dallas on Saturday (Feb. 18).
