Opening with the barnstorming Four Letter Word, Liam immediately rediscovered his iconic swagger and even openly joked with the audience, giving nods to Italian tourists and unable to resist the occasional pop at his older brother and former band mate.
Before introducing the track Man of Misery, Liam asked the crowd: "Have we got any Pretty Green in the house? Or are we not allowed to speak about Pretty Green?"
Earlier in the set during Beatles and Stones he also changed the lyrics to "I can't be bought and sold - like some people" and made a hand gesture which seemingly was a reference to his brother's height.
And on the track The Morning Son - which was written by Liam and is widely believed to be about Noel - he changed the lyrics from "you're blinded by what you idolise" to "you're blinded by what fucking lies".
Bring the Light was the outstanding performance of the night, finding an upbeat Liam on his best form. The rattling piano backing and booming guitar accompaniment rocked the crowd to its core in the stunning Somerset House backdrop.
Not every tune was executed as successfully. Beatles and Stones and Millionaire seemed to get lost in the surroundings, with Gallagher's signature Manc drone sounding like a rusty monotonous freight train, swallowing up the lyrics, which in no way could be deciphered amongst the more casual Beady Eye fan.
That said, it is another successful addition to a growing body of live work by the seasoned veterans. They may not be Oasis, but they still know how to rock 'n' roll.
The band's performance was witnessed by some famous faces including Paul Weller and The Inbetweeners star James Buckley.
