How the hell could one tell what would the PROPER pronunciation be?! American? Well, lets see, I could come up with at least 5 distinct ones... Back to the UK. What region would you pick. Liverpool? N Ireland? Wales? No to mention that in London alone Gillan is being said in so many different ways. But all of these, regardless of the continent are far cry from "Gillian". Don't you think?

Anyway, he is one of the greatest singers ever to hit the hard rock scene. Vocal capacity (unlike Coverdale) as well. Coverdale was good, but not even in the same league. He was not a good choice for an immeadiate Gillan replacement. He is a good singer, but not as gifted so far so voice abititias are concerned. He did better things after his DP departure. Gillan was and is the true Purple. Without him it's a different recipe. And a different meal. A matter of taste...
