Joe Walsh's upcoming blues album will include two songs he's already recorded with Mick Jagger. Walsh, who initially revealed his plans for the album in April, detailed the Stones frontman's contribution:

The song Jagger brought to the sessions is an old one by Howlin' Wolf, according to Walsh. The players -- who include Dr. John, Robert Randolph, Keb' Mo', drummer Jim Keltner, keyboardist Mike Finnigan and former Jeff Beck bassist Tal Wilkenfeld, in addition to Ringo Starr and Jagger -- are so good, Walsh tells us, that he wasn't going to tell them what to play. I just said, "Somebody count off and I'll see you at the end."
