The Wilsons' public debut as a duo took place on Mother's Day at their church. Later at a church Youth Day event, the duo performed "The Great Mandala (The Wheel of Life)" by Peter, Paul and Mary, Elvis Presley's "Crying in the Chapel", and The Doors' "When the Music's Over". The anti-war sentiment, and the irreverence for the venue in some of the lyrics, offended a number of people. By the time they finished, more than half had walked out. Wilson felt some guilt over the event, but "it lit a bonfire under us because we saw for the first time that what we did on stage could have an impact on an audience."
