Ian Gillan (Deep Purple frontman), the original cut from the original album. Became a big hit. Deep Purple going on tour, he could not accept the Broadway run and the movie offer, worldwide casting call was made, Ted Neely slayed it, immortalized the part, still touring the gig today at age 79. Ian Gillan’s scream notes are unearthly and almost supernatural, Ted Neely’s deep, dark notes, expressiveness, and emotive content are unparalleled.
