A former roadie for Winger[3] and "Licensed New Age Healer",[4] John Redcorn is Nancy Hicks-Gribble's Native American[5] masseur, her lover of 14 years (the two split up during the show's fourth season), and the biological father of her son Joseph Gribble.

John Redcorn drives a tan Jeep Wrangler and becomes the lead singer of the band Big Mountain Fudgecake, for which Lucky Kleinschmidt plays guitar and Dale is briefly the manager.

John Redcorn begins singing toned-down solo acoustic children's versions of his songs at the Strickland company barbecue and becomes instantly popular.

A recurring gag is that when he begins speaking about matters related to Native traditions and their spiritual meanings, his long black hair is dramatically whisked up in a breeze.

On one occasion, he finds him trying to sneak inside to have sex with Nancy but thinks he is trying to steal his mower; when Dale reports having a vision of a Native American making love with his wife and Joseph (in full Native American ceremonial garb) being handed to him, he then assumes that means he is part Native American himself; when John Redcorn says straight to a TV camera that "I slept with Hank's best friend's wife for 13 years" with Dale inches away, Dale thinks he means Bill Dauterive's wife and not his.

John Redcorn's access to Nancy is caused primarily by Dale ignorantly allowing him to be her masseur and often trusting her to him to keep her away from other men who may have affairs with her.

It is revealed in Season 6 that Dale believes John Redcorn to be gay, which partially explains his contentment with letting him be alone with his wife so often.

John Redcorn shows special interest in forging a real bond in "Spin The Choice", to no avail—until Nancy takes Joseph aside and sets him straight; it is implied she finally tells him about his true parentage.

Dale Gribble is one individual in particular who has helped John Redcorn research U.S. federal and tribal laws on how to get back his land.
