"The very simple little triads that Freddie Mercury plays in the introduction -- the way he sings it, he just had no limits in his own mind as to what he could do vocally," he said.
"It sounded as if it were effortless the way Freddie sang, like his vibrato would kind of kick in sometimes and sometimes it wouldn't," Connick said. "The way he played piano seemed completely spontaneous, and clearly it wasn't."
'Only the Lonely'
Connick considers the music legend Frank Sinatra "the best of all of the male singers."
"'Only the Lonely' is one of the great musical performances," he said. "The songwriting, the orchestrations, everything was perfect. As somebody who does that for a living, I can tell you it is extremely hard to do what he did, especially when you consider what came before him.
"I mean, I have a lot of information from which to draw," Connick said. "You know, he didn't -- and it's a great masterpiece."
"I had listened to George Jones, but I had never really ... gotten into him," said Connick. "And after I did, I was mesmerized. ... There's a song that he does called 'The Door' and it's incredible. I mean, I've listened to that song 1,000 times and I'm always hearing new things that he does.
"I mean, not to undermine his process, but it seems like there's almost no thought that goes into it," Connick said. "Yet clearly, there is."
