There’s a legal rift between the iconic music duo Hall & Oates — although it's unclear if "Private Eyes" are involved in the case.
Daryl Hall, 77, filed a lawsuit and a request for a restraining order on Nov. 16 against his music partner John Oates, 75.
The pair, one of the most successful duos in rock history, released a stream of hits from the mid-1970s through the '80s, including “Rich Girl,” “You Make My Dreams (Come True),” and "Maneater".
Hall filed the suit, which deals with "contract/debt," in Nashville Chancery Court, according to online court records. The details of the dispute are unclear as the case is sealed.
