The former Oasis frontman is set to launch his solo career this year, and his close friend and fellow rocker has let slip that they will be performing live together at some point in 2017.
Asked whose offer he would accept if both Liam and his brother Noel Gallagher - his former bandmate who he has barely spoken to since Oasis ended in 2009 - Richard said: "I would have
to politely tell them both that I had something else on and stay at home.
"I played a show with Noel a few months ago and I'm playing with Liam later in the year."
The 'Lucky Man' singer told Q magazine: "I wouldn't be daft enough to give Liam any advice on going solo. He can just be himself and do what he loves and people will connect to it. We miss those characters, these people with an opinion. Most people just don't [give an opinion] unless they believe they're getting some sort of PC credit. Then they're out there, appeal after appeal, holding babies and making everyone feel really guilty and miserable around Christmas."
To date, 44-year-old Liam's only announced solo show is at Bergenfest in Norway in June, but Richard, 45, is not one of the artists currently named on the bill.
