This is what we found on Wikipedia regarding the Mouth of the Tyne Festival:

Starting back in 2005, the Mouth of the Tyne Festival takes place every July for a weekend of live music and international street theatre, in the village of Tynemouth. The festival used to take place on both sides of the Tyne, but has made Tynemouth its home for many years now. It consists of spectacular outdoor music concerts at Tynemouth Priory and Castle, cultural performances and a pageant, with other activities at Tynemouth Station and the Playhouse Whitley Bay.

Organised by North Tyneside Council, the 2019 festival was a sell-out featuring Sam Fender, Jack Savoretti, Rick Astley and the Proclaimers, though would be the last festival to go ahead for two years due to Covid. The 2022 festival was scheduled for 8 to 10 July 2022, at Tynemouth Priory and Castle, with headliners including Keane, Lighthouse Family, Sophie Ellis-Bextor announced for the main three-day event and John Cale at the Playhouse on Monday 18 July. One month before the festival was due to take place, Saturday night headliners, the Lighthouse Family announced that they had split up and would no longer be touring. As of 7 June 2022, the organisers, North Tyneside Council, were looking for an alternative headliner, even though Saturday's line-up had been taken off their official website at mouthofthetynefestival.com. In addition, North Tyneside Council said ticketholders could get refunds for Saturday's show.
