Singer Ian Brown has pulled out of a festival appearance over his refusal to play events that "accept vaccination proof as condition of entry".
The former Stone Roses frontman had been due to headline the Neighbourhood Weekender in Warrington in September.
But on Wednesday he told fans the set "will not happen".
Organisers declined to tell the BBC whether audiences would be expected to have the vaccine, but said they would follow government advice.
"No decisions will be taken by government until 21 June at the earliest," it said in a statement.
Brown has been vocal in his criticism of the Covid vaccine, using his Twitter account to protest the idea of a "vaccine passport" and railing against the use of masks to prevent the spread of the virus.
