Audio of the purse-carrying gift from heaven Aretha Franklin's cover of Adele's "Rolling in the Deep" (with a twist of "Ain't No Mountain High Enough") made the rounds on the internet yesterday. Later, she tore the roof off David Letterman's studio when she performed the medley on the Late Show (it's the first release off her upcoming Aretha Franklin Sings The Great Diva Classics album). While her voice has noticably aged and isn't quite as acrobatic as it once was, the woman can still wail. Her pipes remain among our country's greatest natural resources.
