Currently listening to the 50th Anniversary Boxed Set of Jesus Christ Superstar. I'm a hopeless religious romantic! This is the original 1970 version with Gillan's and Murray Head's vocals dubbed over the film scenes. Yvonne Elliman, of course, sang both on the (superior) 1970 original and the 1973 movie soundtrack. I liked the rawness, freshness and tenderness of the original version. It wasn't perfect, but it was organic.
Rumors still abound that a largely unknown Liverpudlian named John was approached to sing the part of Jesus on the original, but he tied it to his wife Yoko (a Japanese performance artist of some note it is said) getting the part of Mary Magdalene. Heavenly powers must have intervened and luckily prevailed. Alas!, and the rest is alternative history we were spared from.
