Rock jock struggles

David Lee Roth, who replaced radio shock jock Howard Stern, has struggled in making the move from rock star to radio host. But during his Friday show the former Van Halen frontman vowed to stick with it.

Roth's show underwent drastic changes last week, with the removal of his three on-air sidekicks and the ditching of background music. Roth said he received four letters in five days from CBS Radio officials demanding changes in his show.
