For the 2006 season, NBC co-produced NFL Sunday and turned it into an abbreviated radio version of its Football Night in America TV pregame, complete with the John Williams-composed NBC Sunday Night Football theme song. Al Trautwig started the season as host of the show, but was replaced by Graham in the middle of the season. The format of NBC NFL Sunday (as the show was called) was slightly different from the format the show used before and after. In addition to the usual format one of the analysts from Football Night in America would appear every week to offer analysis of the game ahead.
