If you've spent your life wondering, gee why has Jack White and Jack Black ever teamed up to produce a song together? Well wonder no longer, as those two Jacks - known as "Jack Gray" - just have done that.
The song is called "Don't Blow It, Kage", and is available now on streaming platforms.
Black and Tenacious D bandmate Kyle Gass recorded the track at White's home studio earlier this year. White has been credited as a producer but if you listen closely you can hear him on the track (around the 1:23 mark).
