He clutched a small carrier bag in his right hand and appeared to be in good spirits as he stopped for a selfie with a fan, while keeping a distance of two metres.

It comes just days after Liam fell out with brother Noel for sharing an Oasis track online for fans. 

Liam Gallagher reacted furiously to his estranged brother’s decision to release a previously unheard Oasis song, Don’t Stop, at midnight on Wednesday.

The 15-year-old demo, which Noel, 52, found in an old box of CD’s, does not feature Liam’s singing at all, nor does it include guitarist Paul Arthurs, also known as Bonehead.

Liam tweeted hours after the release: ‘Oi tofu boy if your gonna release old demos make sure im singing on it and boneheads playing guitar on it if not it’s not worth a w*** as you were LG x.’ 

Nonetheless fans went wild for the release, lauding it for its positive tone, although many noticed that Liam had been left out as Noel sings and plays the music.

They suggested it was a ‘classic Noel song’ and should have found its way into one of Noel’s solo albums and not been hailed as a new Oasis song. 

On Wednesday, Liam had tweeted: ‘Watch out there’s an asteroid about c’mon you know LG x’

Then on Thursday, he seemed to say what he thought of the track and wrote: ‘Zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz.’

Noel had said he had believed the song to be ‘lost forever’ and predicted that fans would argue over their personal reviews.

Tired? Liam seemed to make his feelings on the release quite clear on Twitter on Thursday morning

Meanwhile, Liam announced a free concert at London‘s 02 Arena for NHS staff working on the frontlines of the coronavirus crisis.

The former Oasis frontman took to his Instagram to reveal the news earlier this month as he gushed that it was ‘an honour’ to put on the show as ‘we are very lucky’ to have them during this global pandemic.

Taking place on October 29, all staff who work in NHS hospitals in the UK will be eligible for two free tickets to the show for themselves and a guest.

It has yet to be confirmed if any other musicians will join Liam on stage at the show, and tickets will go on ‘sale’ from 9am on Wednesday 15 April 2020. 

He pleaded with Noel to join him at the charity concert in aid of the National Health Service but later made clear that it would be going ahead with or without his brother.
