Imagine taking your high school chorale on a field trip and this happens.

Emmaus is a small town in Pennsylvania, just next to Allentown, where I used to live. So when I saw this video on Facebook, it caught my attention.

It made me happy to see this young group of people having a great time and putting it all out there while taking a harbor cruise in Boston. Whether it's a speech, a march, or a song about peace- they're making a difference. John Lennon would be proud.
