What an absolute bellend. I find it embarrassing tbh. It's almost like his mgmt have told him 'Right, you need to switch Oasis-era Liam Gallagher back on now. Forget being the half-normal bloke you've been for the last 15 years. Just go back to being as big a kn0bhead as you can, and everyone will lap it up'. He's 51 years old.
Having thought about it, there'll not be many at the gigs stone sober, you go for the atmosphere, I'm sure everyone there will enjoy it, pints of piss an all.
