NASHVILLE, Tennessee: Daryl Hall has accused his longtime music partner John Oates of committing the 'ultimate partnership betrayal' by planning to sell his share of the Hall & Oates duo's joint venture without the other's permission, Hall said in a court declaration supporting his lawsuit to keep the transaction paused.

In the declaration filed Wednesday in a Nashville chancery court, Hall also lamented the deterioration of his relationship with and trust in his musical partner of more than a half-century. The joint venture in question includes Hall & Oates trademarks, personal name and likeness rights, record royalty income and website and social media assets, the declaration states.
