'Our Day Will Come' is dedicated to the shared national aspirations of the Irish and Palestinian peoples. The song title is a direct reference and translation of the traditional Irish Republican slogan Tiocfaidh ár lá.
Video footage showed someone shouting through a megaphone: "Standing with the resistance, we affirm that Palestinians have the right to return to their homeland that was stolen from them during the 1948 Nakba. "We believe in the right to resist by any and all means necessary, for the full liberation and from the river to the sea." Protesters then chanted: "From the river to the sea, Palestine will be free."
