Erhard was performing in at the Anaheim Marriott as part of the National Association of Music Merchant's 2017 convention. When Wonder entered the lobby, Erhard admitted that he didn't know the lyrics to the second verse, according to audience member Marcy Kraft. Wonder then joined the singer onstage after shouting out the Women's March. The pair took turns and Wonder even whispered the lyrics to Erhard during the second verse.
Earlier this month, Wonder made a special appearance on The Tonight Show With Jimmy Fallon to sing "Isn't She Lovely" and "My Cherie Amour" for First Lady Michelle Obama, who was a guest on the show that night. For "My Cherie Amour," he transformed it into "My Michelle Amour" while praising the flustered FLOTUS.
Steve Wonders called on political world leaders and citizens to end "hatred and bigotry of any kind, everywhere."
