Probably not for festivals given they don't really seem to have been that kind of band save for one-offs like Glastonbury 2011 or Bonnaroo in 2017.
In any case, recent interviews given around the 20th anniversary re-release of How To Dismantle An Atomic Bomb say they're still working on a new album and that it sounds like their likely tour for it won't be until 2026. Which is almost a decade on from their last Euro tour tbf - think their last proper Euro run was 2018.
Well pleased with the Paul Heaton announcement. Only seen the fella live once before and had a great time. Could be the first time in my life that I watch every main stage headliner at a festival this.
