Soul singer Charles Bradley has been forced to cancel all of his upcoming tour dates following a second bout of cancer that has made performance difficult. With 37 dates scheduled through the end of the year -- including a number of festival dates in the U.S. and Europe -- a statement from Bradley's spokesperson said the singer began to feel run down during recent shows. A year after a stomach cancer diagnosis, doctors informed him that his cancer had spread to his liver -- though it has not returned ot his stomach.

"I love all of you out there that made my dreams come true,” the 68-year old singer said a statement. “When I come back, I'll come back strong, with God's love. With God's will, I'll be back soon." Bradley, who released his third album, Changes, in 2016, will be taking time off to focus on his treatment and recovery. 

The energetic performer, who has drawn comparisons to James Brown thanks to his excitable stage persona, spent decades working as a chef and playing gigs on the side, before gaining the attention of Daptone Records' Gabriel Roth -- who released the singer's first single, 2002's "Take It as It Comes," which ultimately led to his acclaimed 2011 full-length debut, No Time for Dreaming.
