Republican National Commitee Chairman Lee Atwater says he's "tickled" to be invited to appear on NBC's "Late Night with David Letterman" and play with the "World's Most Dangerous Band."

Atwater, a former rock band member, is to appear on the show Tuesday to play guitar with musical director Paul Shaefer and his band."I'm just tickled to play with what I think is one of the tightest bands in America," he said.Atwater said the appearance came about through his friendship with the group's drummer, Anton Fig. He invited Fig to participate in a rock-and-blues concert he put together as part of the festivities for President Bush's inauguration.
