The Grammy Award-winning musician, who turns 77 in March (17), is being treated for exhaustion in a Los Angeles hospital and has been informed by medics that he cannot perform throughout all of 2017, so he has made the decision to quit touring altogether.

"He is receiving excellent medical care, responding to treatments, and improving slowly," his representatives announced on social media. "The medical team has instructed that he cannot perform any of his remaining 2017 concert date.

"Therefore, with complete sorrow, Al Jarreau must retire from touring. He is thankful for his 50 years of traveling the world in ministry through music, and for everyone who shared this with him - his faithful audience, the dedicated musicians, and so many others who supported his effort."

Jarreau, who won seven Grammys during his five decades in music, pulled out of shows in 2010 after suffering breathing problems and heart rhythm issues, and again in 2012, when he was diagnosed with pneumonia.
