The lead singer of Wilco is disputing the claims in a breach-of-contract lawsuit filed by a former band member who says he's owed royalties.

Former Wilco member Jay Bennett says he deserves money from the band's 2002 documentary "I Am Trying to Break Your Heart." The film documents the making of Wilco's album "Yankee Hotel Foxtrot."

In a statement Tuesday, Wilco's Jeff Tweedy says he doesn't know what the claims are based upon.

He says he didn't produce the movie, has done nothing wrong and hopes the matter will be handled fairly.

According to the suit, Bennett worked as a sound engineer and played instruments for the band from 1994 to 2001.

The lawsuit was filed Monday in Cook County Circuit Court and asks for at least $50,000 in damages.
