The duo took the stage together in Toronto on Wednesday night - kicking off the North American leg of their joint "Legends of the Summer" tour. According to "Billboard," when they were called out for an encore, they ended the night with a mashup of Justin singing Alphaville's "Forever Young" and Jay Z's song of the same name off his "Blueprint III" album.
J-T told Toronto's Rogers Centre to "sing this for Trayvon," while Jay closed the show by saying "Peace and love, we are the legends of summer."
