Pharrell Williams asks for a "framed photograph of late astronomer Carl Sagan" on his rider.
The Happy hitmaker has very specific backstage demands at his concerts and as well as a variety of premium alcohol and health snacks he also always requests the picture of the pioneering cosmologist - whose research was crucial to the surface mapping of Venus and who also wrote papers on the existence of aliens.
Website The Smoking Gun obtained a copy of Pharrell's 2015 rider which included the Sagan image request.
Other items required for the 42-year-old musician include 12 cans of "super cold soda", a litre of Silver Patron Tequila, a bottle of Kettle One vodka, a case of alkaline water, a box of Nilla Wafers biscuits, Cetaphil Cleansing Lotion, fresh ginger root, a jar of grape jam and one loaf of gluten-free bread.
The paperwork also states that Pharrell follows the Atkins Diet - famous for being low in carbohydrates - and needs his food "to be specifically cooked for him on a daily basis at the venues".
