Jonny Goood (Gaga's guitarist) just posted on his IG story that he's going to perform at the Grammys and showed his guitar. Of all 'Joanne' songs performed on JWT he's playing during A-YO, Perfect Illusion and John Wayne so I think we can expect one of those songs  Idk about Angel Down but we can probably exclude 'Million Reasons' and 'Joanne' cuz he's not playing ballads!  I can't wait
