(New York, NY) — “60 Minutes” plans to debut a new Prince album Sunday night. The album, “Welcome 2 America,” was written and recorded in 2010, before the pop star’s 2016 death. It’s not clear why the Minnesota native never released the album. His longtime keyboardist told “60 Minutes” he planned to get back to it later but had moved on to other projects.   Prince died of an accidental overdose of painkillers. His estate is rumored to have thousands of unreleased Prince songs. It is controlled by his sister and five half-siblings, who are in the middle of a legal dispute.
