Beyoncé and Pearl Jam are releasing a single together

It's seems like an unlikely collab, but they're doing it. It's a live cover, recorded at the 2015 Global Citizen Festival, and will be packaged with an unreleased version of "Wishing Well" (from Free, first recorded in '91).

It's coming out as part of Pearl Jam's Ten Club Holiday series, a singles club for members of their fan club (the Ten Club).

In 2013, Eddie Vedder & Co. teamed up with Bey's husband Jay Z for a rendition of his "99 Problems".
