Ozzy Osbourne 's friends came together for another magical tribute ... with Aerosmith's Steven Tyler even getting onstage to show his love for the late rocker.

The tribute kicked off with Ozzy's son Jack and his family speaking to the crowd in a prerecorded message ... saying they couldn't make it, but thanking them for the outpouring of support since his dad passed away. Getty

YUNGBLUD -- an English singer topping the rock charts these days -- came out first ... crushing the iconic "Crazy Train" before Tyler and Aerosmith guitarist Joe Perry slowed the performance down with the song "Mama, I'm Coming Home."

Check out the clip ... Steven's giving it his all on the song -- reaching for high notes and putting his heart and soul into the performance. Getty
