TOM Grennan knows how to turn on the charm.

Opening up his Main Stage set at TRNSMT he tells the crowd: “This is probably my favourite place in the entire planet - Glasgow”.

It’s a bold claim but he backs it up by giving the audience an hour’s worth of solid love.

Rocking a wide legged pant suit, he strips down to a vest about three songs in as the sun finally appears over his set.

Grennan is a seasoned veteran – it’s his fourth time at TRNSMT, as he tells the crowd several times – and he knows what an afternoon Main Stage turn calls for.

Glasgow Times:

The London singer cracks out Don’t Break The Heart and This Is the Place as the crowd swells.

He certainly wins the afternoon as TRNSMT’s chattiest act, giving it the banter in his throaty growl.

TRNSMT, he says, is “back, bigger and better, so good for the Glasgow community and music in general. 

“The sun always shines when I’m here so I must bring the sun with me.”

Headline act Paolo Nutini gets a shout out, as does Calvin Harris during a tribute song.

The boy is pure swagger, delivering each song with a prance and a bounce.

Glasgow, he says, has “the most rowdiest people in the world”.

Glasgow Times:

“I’m pretty rowdy myself,” he adds and there is no doubt about it.

Found What I’ve Been Looking For engages the crowd in a bit of call and response.

Unfortunately, Grennan’s confidence is overblown and a drizzle starts up towards the end of the set.

It doesn’t nothing to dampen the crowd who, by this point, are singing along, moshing and having a fine, fine old time.

As he ends the set with Little Bit of Love – “this is the song that changed my life” – he barely needs to move a muscle as the crowd does it for him, singing the opening lines a capella.

He calls out for Scottish flags to go up in the air, which they do, waving along to end an energising, joyous set, flawlessly delivered from a natural festival showman.
