Singer/songwriter John Mayer recently opened his world tour in Auckland, New Zealand, with a rendition of the hymn “How Great Thou Art” and a traditional kapa haka group performance.

Mayer told the crowd, “Thank you for coming out under such heavy circumstances, it means a lot to me.”

Earlier this month, dozens of people were killed in Christchurch, New Zealand, when a gunman opened up fire on worshippers at two mosques.
