Tom followed in the footsteps of GRAMMY Award winners Alicia Keys and Norah Jones, and dynamic duo Rod Stewart and Jools Holland who previously performed at the busy London 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 smash 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 teamed with slouchy black leather boots.

The American singer displayed her sensational sense of style, adding a black-high neck top to her edgy ensemble. 

Alicia radiated happiness as she posed up a storm in front of the piano and beamed for the cameras after her show-stopping performance. 

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

The singer and the pianist who teamed up for the 13-track record Swing Fever, put on an energetic show with a full band and backing singers.

Supporting them from the crowd, Rod's wife Penny Lancaster, 53, was having the time of her life as she snapped some photos on her phone.

Rod put on a typically stylish display in a cream wool coat, with a pair of skinny jeans and leopard print shoes.

Meanwhile, Jools opted for a navy polo neck top with smart trousers and a long black coat.

In March, Norah, 45, delighted passengers-by as she performed a medley of songs on Elton John's station piano. 

The US musician and nine-time Grammy winner travelled from Paris on the Eurostar to the London railway station to sing and play an exclusive piano rendition of hits Don't Know Why and Sunrise, as well as two songs from her new album Visions. 

Those in attendance 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 passers-by. 

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 lively destination for travellers and shoppers alike.'

'We are delighted that Norah Jones chose to celebrate her new album with St Pancras and we have no doubt that her surprise performance will have brought smiles to visitors at the station and enjoyment to all.'

St Pancras, officially known since 2007 as London St Pancras International, is a major central London railway terminus, based 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 vast array of travellers every year. 

In the centre of the busy station sits a grand piano which encourages impromptu performances, with some stars stunning commuters over the years with surprise performances.
