Obama sings "Amazing Grace"

I already knew President Obama was a good singer from when he sang a line of Al Green's "Let's Stay Together" in 2012, but I was still impressed by his performance in a much lower register during his eulogy for Rev. Clementa Pinckney, who died in the mass shooting in Charleston, SC. While keeping his rendition of "Amazing Grace" simple, solemn, and weighty enough for the circumstances, he did more than singing the familiar melody — he added blue notes and other tasteful embellishments.
