Kanye West was overcome with grief during a performance in Paris on Saturday, just one week after the death of his mother Donda West. The producer/rapper broke into tears while attempting to pay tribute to his late mother -- who died November 10 of complications resulting from plastic surgery -- with the song, 'Hey Mama,' off 2005's 'Late Registration.'

"He just cracked," a concertgoer told PEOPLE. "He was at the end of his concert and had just started to dedicate the song and then he just lost it completely."

After a 60-minute set, West stood quietly onstage while the beginning of the usually celebratory track 'Hey Mama' began. He appeared to sob and was consoled by the guitar player, DJ and a backup singer. The rapper left the stage and returned 10 minutes later to wrap up the show with the single 'Stronger.'

While West continued to fulfill performance commitments in Paris, faculty members, students and friends gathered Friday to pay their respects to the former professor at Chicago State University.

Funeral services for West are scheduled for November 17 in her hometown of Oklahoma City.
