Liam Gallagher has announced a new documentary based around his huge Knebworth shows this summer.Knebworth 22 is a feature-length film documenting the Oasis singer’s return to Knebworth Park, 26 years after his band’s iconic gigs at the Hertfordshire venue.The film will come to select UK cinemas for a limited time from November 17, with a full streaming release on Paramount+ later this year.“I’m still in shock that I got to play Knebworth 2 nights, 26 years after I played it with Oasis,” Gallagher said in a statement. “I’m still trying to get my head around it.“To have played to multiple generations at the same venue so many years apart was beyond Biblical.
