It took almost 6 months, but Prince's final tribute was a monster of a show with huge performances ... despite some big name dropouts.

Stevie Wonder, Chaka Khan, Tori Kelly, and Jessie J ... were just a few of the names that put on the marathon show -- it went for more than 4 1/2 hours inside Xcel Energy Center in St. Paul.

The sold-out show overcame last minute cancellations from John Mayer, Anita Baker and Christina Aguilera

The show ended with "Purple Rain" ... and an ominous recording of Prince's voice saying, "I love you."
