The Piano Guys: how four middle-aged fathers became YouTube sensation
The group have come a long way since their days as struggling part-time musicians, but they haven't forgotten what brought them together in the first place: making joyous music

- Steven Sharp Nelson, Jon Schmidt, Al van der Beek, and Paul Anderson - may not ring any bells, but The Piano Guys, as they are known collectively, have been taking the internet by storm. Capturing a vast online audience with their unusual takes on classical and pop tunes, these four ordinary blokes from the American state of Utah are now one of the biggest YouTube sensations, having more than 3.7 million subscribers and 500 million views (and still counting) to date. And on April 18, they'll bring their act to Hong Kong.
When the outfit - pianist Schmidt, cellist Nelson, songwriter/producer Van Der Beek and videographer Anderson - formed in 2011, they never imagined it would lead to a world tour (there will be more Asian, US and European dates after Hong Kong). They were, at the time, just part-time musicians juggling day jobs and family - they have a combined total of 16 children.
"At first we were just doing it for fun," Nelson, 37, tells 48 Hours as he recalls the group's humble beginnings. "It was tough to make ends meet as a musician, so I had a day job and played music on the side, I never anticipated that The Piano Guys would become full time."

"I never thought we would tour this much and I never dreamed of going to Hong Kong as a performing cellist. None of us have been to Hong Kong before, so we'll probably be travelling around the city," he says.
For the upcoming concert, Schmidt and Nelson will be performing tunes from their previous albums, including YouTube Hits Volume 1 (2011), The Piano Guys (2012) and last year's Wonders. Van Der Beek and Anderson will be joining them on stage to play the group's breakout hit, an instrumental version of One Direction's What Makes You Beautiful, which has garnered more than 38 million views on YouTube.
