In an announcement that few would have envisioned when Last Comic Standing 4 first premiered in June, NBC has announced that former Last Comic Standing host Jay Mohr and first season winner Dat Phan will perform on next week's special 90-minute finale of the show's fourth season.

In addition to Mohr and Phan, second and third season winners John Heffron and Alonzo Bodden will also perform during Last Comic Standing 4's finale, which will air Wednesday, August 9 at 8PM ET/PT and reveal show's fourth season champion (Last Comic 4's penultimate episode, which will reveal the competition's final two comedians and feature their final performances, will air in the show's regular time period on Tuesday, August 8 at 9PM ET/PT.)

Back in 2004, Mohr, who in addition to hosting Last Comic Standing's first three editions, also helped create the series, had been an outspoken critic of NBC's handling of Last Comic 3, the hastily-assembled Fall 2004 edition that the network later pulled from the air with only one episode remaining.

Although Mohr still retained a consultant credit when NBC decided to resurrect Last Comic Standing for a fourth edition, he hasn't been involved with the current season and Anthony Clark replaced him as the show's on-air host. As recently as a few weeks ago, Mohr told that he had "no interest" in the current season.

Unlike Mohr, Phan (widely considered the show's least successful winner) hasn't bourne Last Comic Standing any animosity -- if anything, the situation has been reversed. During the fourth season's premiere, the show's producers omitted any mention of Phan from an opening segment that touted the competition's previous winners.

Last month, NBC announced that, happy with the ratings that this summer's Last Comic Standing revival has drawn, a fifth edition of the show will air part of NBC's Summer 2007 primetime programming.
