Jagger solo album may feature Bono

(Launch) - The solo album Mick Jagger is working on gets more star-studded at every turn. Word out of Europe is that Jagger and U2 frontman Bono recently spent some time together in a studio in Cologne, Germany, laying down vocals for a song on the still-untitled collection. It would be payback of sorts, as Jagger and his daughter Elizabeth recorded some vocals for the song "Stuck in a Moment You Can't Get Out of" that U2 eventually decided not to use. There's no release date for the Jagger solo project, which will also feature contributions from Who leader Pete Townshend, along with the rumored involvement of Lenny Kravitz, Matchbox Twenty frontman Rob Thomas and hip-hop queen Missy Elliott.
