But as he was tapping away at the keys, two people stopped to listen.
One of them even began recording his performance.
It didnt end there.
The other guy then stood next to Spencer at the bench and started playing along.
The man playing the piano with Spencer was The Lumineers' co-founder, Jeremiah Fraites.
They overheard Spencer’s rendition of Ophelia and went to watch him play for the ultimate surprise.
The official Lumineers Instagram shared a video of the chance duet.
Sutton Bell, recognizing that Spencer doesnt place Fraities, tells Spencer, This is his song.
Spencer knew there was something different about the stranger who stood alongside him.
He not only played the song perfectly, but he had an air of familiarity about him.
Spencer shared the now-viral video on Reddit, where he relays the encounter with the musical star.
He was so nice!Spencer wrote.
When I came back they were still there listening to other people play the piano.
