Daryl Hall

Recently filed lawsuit claiming a breach of contract pits long-time partners against one another.

Hall says his bandmate tried to "ambush" him with a catalog sale in an attempt to "cause me the maximum amount of harm."

Hall obtained a temporary restraining order against Oates earlier this month.

He's said "it's very annoying to be a duo."

Planned album could also include a fresh collaboration with King Crimson's Robert Fripp.

New tour will feature guest appearances from former Hall and Oates producer Todd Rundgren.
