Jack White has revealed to BBC 6 Music that Radiohead have recorded at his Third Man Studios.
"I didn't play with them or produce it, but they came and recorded at Third Man," White said.
Radiohead vocalist Thom Yorke raised suspicions that the band may have been collaborating with White when he announced onstage at Bonnaroo, "This song is for Jack White. We saw him yesterday. A big thank-you to him, but we can't tell you why. You'll find out."
