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:

“He brought in a song and he played great harmonica and we wrote a song. Keb’ Mo’ and Bill Withers came and we all kind of wrote a song, “Over My Head.” I’m a full-time Eagle right now, hopefully I’ll get back to it. Don Was is producing it and, hopefully, end of the year.”

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 said 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.”
