The Hold My Hand hitmaker had been due to appear at the Sundown Festival at the Norfolk Showground in Norwich, England on Saturday (05Sep15), but disappointed gig-goers with a no show.

Glynne apologised to fans on, writing, "So sorry I can't be with you at Sundown today. My doctors tells me (sic) that I have post operative fatigue and stress and urgently need to rest. Although my voice is better, my body just needs a little more time to fully recover from the operation."

The chart-topping singer had to pull out of a succession of shows after undergoing throat surgery in June (15) but returned to performing with a set at Britain's V Festival last month (Aug15). Glynne was replaced on the Sundown bill by fellow British star Becky Hill.
