Legend, who was hosting the annual event, was joined by Underwood for the final performance of the night. The song's powerful lyrics were perfectly fit for the theme of the organization, which works to bring hope, especially following a year of uncertainty and hardships.
"Ooh, let there be peace on earth / Let the lonely join together, let them know their worth / Ooh, let the children know / There's a brighter day ahead, let's hold on to hope / And on the coldest evening in this December / Let us pray the spirit of love will linger," the two sing.
"A dreamy winter backdrop ❄️ + The silky smooth vocal stylings of @carrieunderwood and @johnlegend �� = A jaw dropping performance of ‘Hallelujah’ ��," Global Citizen wrote on
