At dedication of Manti Temple, some hear heavenly choir, while others see bright halos of light around apostles Lorenzo Snow, John W. Taylor, Heber J. Grant, John Henry Smith, and Seventy's president Jacob Gates, and dimmer halo around Apostle Francis M. Lyman's head. Some say that John W. Taylor's "voice was exactly like Joseph the Prophet" and that Lyman's voice is that of Brigham Young. While in temple, Woodruff "Consecrated upon the Altar the [brown] seers Stone that Joseph Smith found by Revelation some 30 feet under the earth."
