More than $700,000 was raised by a special concert at T-Mobile Arena in Las Vegas, which included a video clip of Elton.
The show was held earlier this month, in honour of the victims of the deadliest shooting in modern U.S. history. On the first of October, a gunman opened fire on a music festival crowd from the 32nd floor of the Mandalay Bay Resort and Casino.
Proceeds from the T-Mobile Arena benefit went to the Las Vegas Victims Fund.
The event featured more than a dozen A-list entertainers and homegrown talent, drawing a capacity crowd of 12,000 guests.
"We are grateful for the outpouring of love from these icons of Las Vegas entertainment, who once again proved that our community stands as one to support the victims of this senseless tragedy," said Clark County Commissioner Steve Sisolak, who organised the Fund with Sheriff Joseph Lombardo.
The lineup included performances by the Killers; Imagine Dragons; Boyz II Men; David Copperfield; Penn & Teller; Carrot Top; Cirque du Soleil; and the Blue Man Group.
Celine Dion and Elton were among the artists who sent recorded messages. The latter was introduced by Wayne Newton and appeared via video to send his love and support.
He performed Your Song and Don't Let The Sun Go Down On Me.
