William Hayes (Jan. 26, 1708 - July 27, 1777) was an English composer, singer, organist, conductor and author. He spent  the majority of his time and musical efforts as an organist.

Hayes spent the beginning of his work life as an organist in several different churches, and later on spent the majority of his career at the University of Oxford, where he was the organist of Magdalene College. He earned two degrees while there, and was elected to be Heather Professor of music, along with organist of the University Church of St. Mary the Virgin in 1741. He would be of great importance to Oxford for the next three decades, helping to build an important music room (chamber music hall) and joining some elite musical clubs.

When it came to composing, Hayes wrote both secular and sacred music, and instrumental works as well. In addition to composing music, he was also an author of three books, all about music.  The Thirsty Vampires is a work with three parts/lines. Written in G major, the opening line outlines the key, the second is similar, and the third moves in the beginning in a scale-like fashion. The words are:

Line 1: The thirsty Vampires some believe, their Graves can pierce and Coffins leave,
to suck poor Mortals dry.

Line 2: If I've the Luck to drink when dead, my Liquor shan't be Blood tho' red.

Line 3: The Juice of Grapes best suits with me, to some huge Cask of Wine I'll be,
I'll be a Vampire when I die.

We unfortunately couldn't find a recording of this work; we hope that changes one day!
