Comedian Frank Caliendo returns to Wisconsin this week for shows Friday and Saturday night at the Riverside Theater.

But, he'll need to warm up a little bit first.

Caliendo is slated to appear on "Late Show with David Letterman" tonight on CBS (Channel 58). Actress Katie Holmes, aka Mrs. Tom Cruise, and Maroon 5 will join Caliendo in the green room (and on the show).

Caliendo's sketch comedy show "Frank TV," heads into reruns in the coming weeks. Caliendo shot five of the eight installments of the series, which was heavily promoted by TBS, but had to shut down production due to the Hollywood writer's strike.
