It was always going to happen sooner or later… the two greatest piano players on YouTube have collided and created a video so foot-tappingly brilliant, you may need to have your internet privileges removed or you will never get anything done again.
Brendan Kavanagh is an Irish pianist who is an internet sensation thanks to his inspiring videos where he interacts with the public and wows them on the pianos of the London train stations.
He is an incredibly talented player, and also a genuinely warm personality who is always trying to tease out and encourage the talents of those he meets.
Well, talent is the one thing that his new best buddy is not short of. Thomas Krüger, aka Mr Piano, is another hugely accomplished YouTube star.
Kavanagh is known as Mr Boogie for his love of playing Boogie Woogie, whereas Mr Piano is more inclined to re-imagine popular dance anthems on the piano.
Despite their varying styles on the ivories, the collaboration is simply stunning.
The two met up in London to play one of the station pianos, and the results are just as fantastic as you could expect.
They combined to play a medley of the classical favourite Greensleeves, and then Take On Me the famous pop song by Norwegian band A-ha.
Get your feet somewhere comfortable, cos they are about to develop and rhythm and mind of their own.
