For one night only, Hal Holbrook, best known for impersonating Mark Twain in a solo show, will bring that very monologue to the Denver Cenver For the Performing Arts' Buell Theatre, April 4. A box office spokesperson told Playbill On-Line (April 4) seats are still available, but only in the upper balcony.

Holbrook started doing Mark Twain Tonight! 46 years ago and even won a Tony Award for it. He's also appeared in the national tour of Death Of A Salesman, The Apple Tree and, most recently, Wendy Wasserstein's An American Daughter. In 1990 he played King Lear at NY's Roundabout Theatre. A member of Lincoln Center Repertory Theatre from 1963-65, Holbrook has five doctorates, including an honorary doctorate from Ohio State University. He made his Broadway debut in 1961's Do You Know The Milky Way?.

Mark Twain Tonight! -- which also played the Buell Theatre for a night back in November 1997 -- is taken from hundreds of newspaper articles penned by Twain, not to mention excerpts from such novels as Tom Sawyer, The Adventures Of Huckleberry Finn, The Prince And The Pauper and Life On The Mississippi. Each evening is different for Holbrook; he has 12 hours of material to choose from, six of which he keeps in his head. The performance itself runs two hours.

For tickets ($25-$40 and information on Mark Twain Tonight! at the Denver Center on Champa St., in Denver, CO, call (303) 893-4100.
