Mick Jagger says he will appear on Concertina Jack, the upcoming studio album from his brother, Chris Jagger.
"My brother Chris Jagger has a new album called Concertina Jack, & I'm singing on the title track," wrote Mick on his Twitter page.
According to Chris, the album, his ninth solo effort since 1973, marks an anniversary for him.
"I'm not a big one for anniversaries, but in the brew ha ha revolving around The Rolling Stones and 50 years I realised it's 40 years since my first record came out," he said.
Mick is featured on a second cut on the album called "Diamonds and Pearls."
The LP is named after a great uncle who left his family home in the U.K. to sail to Sydney, Australia around 1880.
