After video message by Jack Osbourne and his family, as well as a video montage of Ozzy through the years, Yungblud kicked off the VMAs musical tribute by singing “Crazy Train,” with Extreme guitarist Nuno Bettencourt leading the backing band.

Yungblud strained a bit singing “Crazy Train,” but did a stellar job on the next song, Black Sabbath’s “Changes,” which he also sang at the Back to the Beginning concert earlier this summer.

Tyler then walked onstage with his Aerosmith bandmate Joe Perry to sing “Mama, I’m Coming Home.” The singer, whose vocal injury forced Aerosmith to retire from touring last year, delivered the Ozzy ballad with a heartfelt rasp, and was joined by Yungblud for the second half of the song.

The tribute ended with video of Ozzy in concert, saying, “Thank you, goodnight. We love you all. God bless you!”
