Elton John will host an all-star benefit special aimed at providing some relief and entertainment for Americans locked down in their homes during the coronavirus pandemic.

The performances will be filmed on the singer's personal cell phones, cameras and audio equipment in order to ensure the health and safety of the participants in this period of social isolation. It will air on Fox in the original slot for the canceled 2020 iHeartRadio Music Awards -- March 29 from 9-10 p.m. EST -- and on iHeartMedia radio stations nationwide, as well as on the IHeartRadio app.

The concert will also pay tribute to the front line health professionals, first responders and local heroes who are putting themselves in harm's way to help others, encouraging viewers to support two of the many charitable organizations helping victims and first responders during the pandemic: Feeding America and First Responders Children’s Foundation.

Fox will offer the event across all its linear and digital platforms, with additional details and performers to be announced soon; check here for updates.
