He became a member of the Kawaihau Glee Club, sponsored by the Prince and his friends, which competed with the singing clubs of the king, Princess Liliʻuokalani and Princess Likelike. Liliʻuokalani noted her brother's group "consisted in a large degree of the very purest and sweetest male voices to be found amongst the native Hawaiians".
