Oasis may have kicked off their tour, but fans can still get involved this week if they know where to look, and if they hold on to some patience.

Liam Gallagher made a cheeky reference about high ticket prices for Oasis’ reunion tour during opening night in the U.K. Liam, 52, joked about the expensive tickets for the show onstage as he and his brother Noel Gallagher, 58, performed together for the first time in 16 years in Cardiff, Wales, on Friday, July 4.

The pioneering Britpop band’s world tour — marking the first time famously feuding brothers Liam and Noel Gallagher have played together since 2009 — kicks off on Friday night in Cardiff, Wales, at Principality Stadium. Richard Ashcroft from the Verve is the opening act alongside Liverpool-based band Cast.
