The family of Gap Band members Robert and Ronnie Wilson have filed a lawsuit against BMG for unpaid royalties on the Bruno Mars and Mark Ronson 2014 song “Uptown Funk.”

Rolling Stone reports that BMG has “failed and refused” to pay the Gap Band heirs, Ronnie’s widow Linda Wilson, Robert’s daughter Robin and LaTina, and other family members. The family filed the suit this week, claiming that BMG has either “retained all funds due to plaintiffs for its own benefit and enjoyment” or “wrongfully diverted” the money. The Gap Band’s third member, Charlie Wilson, was not named in the filing.

The complaint reads, “Despite its obligations to account for and pay to plaintiffs their share of all income received from the ‘Uptown Funk’ musical composition, BMG has refused and failed to provide either the funds due to plaintiffs or an accounting, despite plaintiffs’ repeated demands therefor.”
