Ellie Stamp was told that she is the secret love child of Elvis. Since then she has been trying to discover how and why delusional beliefs occur. Are You Lonesome Tonight is a solo interactive performance, created with neuroscientist research partners and based on true events. It utilises Ellie’s skills in immersive theatre, game play, visual imagery and music to examine current methodology used to define and measure madness. She invites the audience to explore her lineage to The King by playing with nine numbers that fascinated Sir Issac Newton, Pythagoras and Elvis.
