Lynott fits the sound of Thin Lizzy, Bush has a nice powerful voice, and Breed I’d never heard of before, but that song showcased some good vocals (and a lot of Maiden inspiration). Still, I’m going with the King Diamond vote and giving it to Byron. I love his lush and rich voice. He can’t belt down the walls, nor are his highs that great, but he makes up for it with having a really really nice texture when singing at his main level. He’s like an Ian Gillan who can’t hit all of Gillan’s notes, but instead focuses on making his lower range stand out.
