NEW YORK -- For English singer Rita Ora, this week is both emotional and exciting.

Ora is one of the 50 artists singing Simon and Garfunkel's "Bridge Over Troubled Water," a charity music single to help the victims of the fire at Grenfell Tower that killed at least 79 people last week. The song was released Wednesday, just a day before Ora's new show, "Boy Band," premieres on ABC and she drops the video for her new single, "Your Song," co-written by Ed Sheeran.

The 26-year-old, who is from London and grew up near Grenfell Tower, said she cried while recording her vocals for the song.

The song is produced by Simon Cowell and includes vocals by Robbie Williams, Jessie J and Liam Payne.
