^When describing a total solar eclipse, Close wrote: "It was simultaneously ghastly, beautiful, supernatural. Even for a 21st century atheist, the vision was such that I thought, "If there is a heaven, this is what its entrance is like." The heavenly vision demanded music by Mozart; instead we had the crickets." Frank Close, 'Dark side of the moon', The Guardian, August 9, 2001, Guardian Online Pages, Pg. 8.
