David Letterman is a well-known television host and comedian. He hosts the talk show, Late Show with David Letterman which is broadcast on CBS.  Letterman has been a fixture on late night television since the 1982 debut of Late Night with David Letterman.    Johnny Carson, who was Letterman’s friend and mentor, is the only person to have a longer late-night hosting career.

Letterman is also a television and film producer. His company, Worldwide Pants, produces his show and The Late Late Show With Craig Ferguson. Worldwide Pants has also produced several prime-time comedies, including Everyone Loves Raymond and Ed.

Letterman’s shows have received 67 Emmy Award nominations, winning twelve times in his first 20 years in late night television. From 1993-2009 Letterman ranked higher than Leno in the annual Harris Poll of Nation’s Favorite TV Personality twelve times.

Letterman has a private foundation called The American Foundation for Courtesy and Grooming. Through it, Letterman has donated millions of dollars to charities and other non-profits in Indiana and Montana, celebrity-affiliated organizations, universities, and other organizations such as the American Cancer Society, the Salvation Army and Doctors Without Borders.

On November 24, 2003, Clay Aiken was a guest on David Letterman’s Show.  Clay was in New York still doing some promotion for his album, Measure of A Man.

Unlike Leno and Kimmel, David Letterman is reluctant to have his musical guest sit down and talk.  But, Clay was an exception.  Even though his time sitting with Letterman was very short, Clay did get a few moments to chat with the host.

Clay followed Paul Newman on the show and sung a great rendition of his hit song, Invisible.

All in all, it was a wonderful night and one that was watched by many people.  Letterman’s ratings were very high that night.
