There are gigs that feel big, and then there are nights like this. Tom Grennan’s sold-out show at The O2 London wasn’t just a headline gig, it was a full-blown celebration of connection, chaos, and certified bangers. From goosebump-inducing moments to wild pyro-drops, it was the kind of show that left people smiling and sprinting to beat the crowd.
Starting the night with zero gimmicks and maximum vocal power, Allie Sherlock stepped into the spotlight with nothing but her guitar and an emotional setlist. Bathed in soft purple and white light, she glided between cleverly chosen covers and her own heartfelt originals.

A standout moment? Her intro to ‘Black Friday’ by Tom Odell – a song she found on TikTok, obsessed over, and now dreams of performing in a venue like this. And honestly, it belonged there.
She closed her mini-set with her debut single ‘How Love Works’, stepping down the runway into the crowd as red spotlights bathed the arena. Fans lifted their phone torches in a goosebump-perfect moment that’ll 100% blow up on socials.
Tom Walker brought his signature raw edge to the O2 stage, lacing emotional grit with that unmistakable powerhouse voice. Playing his famous ‘You and I’, he turned the crowd into a sea of flashlights and phone screens, making sure every single voice in the room felt part of the moment. There’s something about the way Tom delivers a lyric, like it’s been lived in, worn down, and still glowing.

Now onto the main man. Tom Grennan came on like a rocket, no messing around, just straight into pure joy. Within minutes, the crowd was bouncing, the lighting rig was doing the most, and Tom was all over the stage, leaping, shouting, and waving at every corner of the arena like he’d just spotted long-lost mates.
There was an extra-special moment early on when Tom dedicated the song ‘Crown Your Love’ to his daughter in the audience, with arms in the air and emotions running high. And yeah, we all felt it.

From ‘Royal Highness’ with its explosive red lighting and crowd-led vocals, to the golden-hued singalong of ‘Somewhere Only We Know’, the setlist just didn’t miss.
“This is wild… LOOK AT MY NAME IN LIGHTS UP THERE!” Tom shouted at one point, clearly caught up in the moment. And so were we. Even after multiple tours and festival slots(and we have been there for most of them!), this show felt like his moment, a man fully in his prime, owning the biggest stage in the country.

He brought out his mate Angel to duet on ‘Let’s Go Home Together’, hugged it out mid-stage, and then ramped everything up again with ‘Diamond’, ‘All Goes Wrong’ (complete with a dramatic backwards roll on stage), and the synth-sparkling ‘Lionheart’.
And just when we thought it was over…
Tom closed the night with ‘I Won’t Miss a Thing’ and, of course, ‘Little Bit of Love’, complete with confetti, fireworks, and the classic “everyone get down then JUMP!” moment that left the floor shaking.

He ran to the barrier to thank fans face to face, sweaty, beaming, and clearly emotional, calling it a night he’ll never forget. Honestly? We won’t either.
