Denyce Graves "Ave Maria"

American Mezzo Soprano Denyce Graves sings "Ave Maria" by Vladimir Vavilov arr. John Conahan in 2013 Christmas at Belmont concert, Belmont University, Nashville, Tennessee, USA broadcast on PBS. There seems to be a musicologist skirmish as to whether this Vavilov composition was falsely attributed to Giulio Caccini. I just transcribed the attribution from the broadcast video.
