Totally agree, I’m surprised he hasn't been mentioned more often.
Roy Orbison hardly has to open his mouth and there is rich sound pouring out.
I like to compare him to the annoying Bruce Springsteen in Black and White night
(no offence to Bruce fans)
Others that have already been mentioned here like Elvis, Freddy, Frank S. etc., all have great voices too, much better ‘male’ singers today, in 2005.
I also like male vocalists like Andrea Bocelli, but he isn’t exactly Rock&Roll or R&B
Cheers
