ThePianoGuys (esp. Steven Sharp Nelson): "Beethoven's 5 Secrets" and "The Cello Song"

Okay, so I am an unabashed fan of ThePianoGuys, but I think I may have come across them in an unusual way....  I recently started a research study on back pain in cellists.  While I was preparing, I thought, "I should look at some videos to see how different cellists move the bow when they play."  I did a YouTube search for "cello," and the video below came up in the list.  The thumbnail image showed eight cellists, and I thought, "Perfect!  I can watch eight cellists at once."  Of course, it wasn't long before I realized what was happening....

Also when I was preparing for the study, I realized that the song "Secrets" by OneRepublic had a great cello part (I thought I could learn to play it ;), and I hoped that one day ThePianoGuys would do a cover of that song.  Well, today that became reality!
