DVR ALERT: Billy Crystal Visits CBS' LATE SHOW with David Letterman Tonight 1/12

Billy Crystal visits The Late Show with David Letterman tonight, Monday January 12th at 11:30pm (EST).

Billy Crystal won the Tony award and broke box office records with his Broadway hit 700 Sundays.

Crystal, an eight-time host of the Academy Awards ceremony, starred in 'Soap' in the 1970s, before becoming a regular on "Saturday Night Live." He has appeared in films including Analyze This, Throw Momma From The Train, Deconstructing Harry, and City Slickers. His autobiographical one-man play, 700 Sundays, won him a Tony Award and became the highest grossing non-musical in Broadway's history.

David Letterman marks his 25th year in late night comedy on Feb. 1, 2007, and this year also marks his 14th year as the host of the LATE SHOW with DAVID LETTERMAN on CBS. After more than 4,500 late night broadcasts, he remains one of the most influential personalities in the history of television. Other than the late Johnny Carson, who hosted "The Tonight Show" for 30 years, no late night host comes near Letterman in longevity, critical praise and award recognition. Often imitated but never matched, Letterman presents, night after night, an unpredictable hour of innovative comedy.
