In this pilot Will discloses he was court-martialed from the army during Vietnam, however this isn't touched upon during the regular series. We also learn that Sonny Pruitt lost a son in Vietnam and spent time in prison for a charge that was unspecified.
Theme song, 'Movin' On,' was written and performed by country music legend Merle Haggard.
In the Season One's "Good for Laughs", as Will is attempting to get Sonny and Tucker released from jail, he states that Tucker "stood by me in 'Nam", an oblique reference to his court martial.
