Tom Grennan delights commuters as he performs new Christmas single in London’s St Pancras train station

Tom Grennan shocked Londoners on Thursday when he performed an impressive impromptu festive performance at St Pancras Station.

The 29-year-old singer brought the Christmas spirit with a captivating performance of his brand new Christmas single It Can’t Be Christmas, alongside some of his most popular hits including Little Bit Of Love and his latest single Higher.

The star dressed warmly for the performance in a burgundy Stone Island jacket and flared black trousers.

To complete his look, he opted for yellow-tinted sunglasses and wore a black baseball cap.

Tom looked in his element as he was joined by several backing singers and a guitarist who put on a breathtaking performance for passers-by.

The new single has become an instant Christmas classic and can now be streamed exclusively on Amazon Music.

Tom follows in the footsteps of GRAMMY Award winners Alicia Keys and Norah Jones, and the dynamic duo of Rod Stewart and Jools Holland who previously performed at London’s busy train station.

Last year Alicia, 43, showed off her skills on one of the pianos at St Pancras Station.

As crowds of commuters gathered, the hitmaker performed her hits Empire State of Mind, If I Ain’t Got You and No One.

She was pictured wearing a leather car racing jacket and a black skirt which she paired with sloppy black leather boots.

The American singer showed off her sensational sense of style and added a black high-neck top to her sharp ensemble.

Alicia radiated happiness as she posed up a storm in front of the piano and beamed at the cameras after her breathtaking performance.

In December last year, Sir Rod, 79, and Jools, 66, surprised fans with an impromptu performance.

The singer and pianist, who collaborated on the 13-song album Swing Fever, put on an energetic show with a full band and backing singers.

Rod’s wife Penny Lancaster, 53, supported them from the crowd and had the time of her life as she took some pictures on her phone.

Rod put on a typically stylish presentation in a cream wool coat, skinny jeans and leopard print shoes.

Meanwhile, Jools opted for a navy blue turtleneck top, smart trousers and a long black coat.

In March, Norah, 45, delighted passers-by when she performed a medley of songs on Elton John’s piano.

The American musician and nine-time Grammy winner traveled from Paris to London train station on the Eurostar to sing and perform an exclusive piano rendition of the hits Don’t Know Why and Sunrise, as well as two songs from her new album Visions.

Attendees could be seen smiling, leaning in for a closer look or recording the singer in action on their phones.

The star looked in her element as she belted out some of her best hits to passersby.

Wendy Spinks, commercial director at St Pancras and HS1 Ltd, said at the time: ‘Our station is proud to host public performances, creating an exciting and vibrant destination for travelers and shoppers alike.’

“We are delighted that Norah Jones has chosen to celebrate her new album with St Pancras and we have no doubt that her surprise performance will have brought smiles to those at the station and fun for all.”

St Pancras, officially known as London St Pancras International since 2007, is a major railway station in central London, located in the London borough of Camden.

It is the terminus for Eurostar services from Belgium, France and the Netherlands to London, meaning it welcomes a large number of travelers every year.

At the center of the busy station is a grand piano that encourages impromptu performances, with a number of stars wowing commuters with surprise performances over the years.
