Lynne, the frontman of the British rock band Electric Light Orchestra (ELO), was supposed to have his last live performance — and headline — at the BST Hyde Park festival on Sunday and was closing out his “Over and Out” farewell tour. However, it’s canceled due to his health issues.

"Jeff has been battling a systemic infection and is currently in the care of a team of doctors," organizers wrote on July 12.

BST Hyde Park has cancelled the final day of its festival after Lynne, 77, withdrew from the band's headline slot at the last minute due to health concerns. He had been due to front the rock band on Sunday, but stepped back on the advice of his doctors following a "systemic infection", according to a statement released by ELO.
