Kenny Chesney has confirmed his involvement in a Jan. 15 telethon to benefit tsunami victims in Southeast Asia. “You watch this stuff on TV,” Chesney said. “You look at the pictures in the paper … and you can’t even imagine how those families must feel. Truly, it is beyond comprehension. So when the people putting this show together called to ask, I didn’t even have to think about it. I was like, ‘Where do you need me to be?’” The one-hour program featuring Christina Aguilera, Sheryl Crow and actor George Clooney will be telecast on NBC and its cable channels — the USA Network, Bravo, Trio, Sci Fi, MSNBC and CNBC.
