MORE than 200 performers from the York area will be joining a line-up of rising opera stars at this year’s York Proms picnic concert. The York Proms is hosting its biggest ever community stage when it returns to the Museum Gardens on Sunday 27 July, alongside its live orchestra and professional soloists. The York Philharmonic Male Voice Choir, who are celebrating their centenary year, will be performing the National Anthem with the orchestra to open the show when it takes place for the seventh time.
