Country Stars have joined several other artists to help the Red Cross with relief efforts in Japan after last month’s earthquake and tsunami. Stars have donated items to be auctioned off through an online auction operated by eBay. Items donated include two tickets to a Keith Urban show with a private meet and greet, handwritten lyrics to Beautiful World by Dierks Bentley, a football signed by Darius Rucker, and an acoustic guitar signed by the members of Lady Antebellum. The auction is being presented in two phases between now and April 21. To learn more or place a bid, click here.
