Singer also covered Chaka Khan's 'I Feel For You'
The British singer was originally meant to perform at Worthy Farm last year but was forced to cancel in order to undergo vocal surgery.
Performing on the Pyramid Stage, Glynne told the crowd: “Two years if someone told me I’d be standing on this stage, singing to this many people, I’d be like ‘Shut up!'”
“I’m here to bring love and happiness because the weather is so awfully shit,” she added.
During her set, Glynne’s backing band played a snippets of Drake’s mega-hit ‘Hotline Bling’ (watch footage below), as well as ‘Uptown Funk’.
Glynne also covered Chaka Khan’s ‘I Feel For You’ during the set.
