Leonard ‘Hub’ Hubbard alleges that he’s owed money from the band

The Roots’s former bassist Leonard ‘Hub’ Hubbard is suing the band’s current manager and two of its members, Questlove and Black Thought.

Hubbard, who joined the Philadelphia band in 1992, left in 2007 after he was diagnosed with multiple myeloma, a form of blood cancer. The illness forced him to leave two years before the Roots became Jimmy Fallon’s house band.

The suit alleges that under a deal with the band Hubbard would continuing being paid as a co-owner. But Hubbard claims that a former manager for the Roots sent him a letter in 2014 threatening to cut off his health insurance and his share of their revenue.

The Roots have not yet commented on the lawsuit.

Hubbard has played on seven of the Roots albums, his last being 2006’s ‘Game Theory’. A year after his departure, he reunited with the band at the 2008 Roots Picnic for a performance of ‘Mellow My Man’, making a latter appearance in 2010.

The Roots have released four albums without Hubbard. They are currently the house band for ‘The Tonight Show’ after Jimmy Fallon’s move from ‘Late Night’.
