Forgive me if this is old news, I looked but didn't see a link here (I could have missed it, of course).
The group is Boyce Avenue. This is the best cover of Faithfully I have ever heard. Notes are spot on, and the instrumentation is nice as well.

And for kicks, With Or Without You from U2, with female vocalist Kina Grannis:

Again, sorry if this is old news. When I hear good music, I want to share it. Of course, musical taste is very subjective.

I have already purchased 9 songs from these guys. This stuff is right up my alley. Their cover tunes are well done. I actually like Fast Car now (never was a Tracy Chapman fan, but they make the song much better)
Again, with Kina Grannis:
