POISON - Open Up And Say Pay Me

TMZ.com reports:

POISON is set for a new tour this summer, but first they're getting the band back together to sue their record label!

According to a lawsuit filed today in L.A. Superior Court, the band claims Capitol Records stiffed 'em - underpaying them royalties for years. They also claim they were shortchanged by EMI Music Marketing over a deal they made in 2005 for their greatest hits album, which featured a new track entitled 'We're An American Band'.

They're suing for breach of contract and seeking damages in excess of $25,000.
