Mike Massé is just blowing me away with his pizzeria cover songs. This guy can honestly do covers that are better than the originals, and he does them acoustically.
I would pay top dollar to see this guy perform. This is a cover of "Don't Fear the Reaper," made famous by Blue Oyster Cult and Will Ferrell.

Watch here, as he covers "Linger" made famous by the Cranberries, with Brenda Andrus and Jeff Hall. You should also note that he's doing the background vocals here, it's not a backing track.

Now, here is the video that first set me on to Mike Massé. It's a cover of Simon and Garfunkle with Jeff Hall.
