That said, I enjoy Freddie Mercury, Elvis Presley, Paul McCartney, [Nazareth singer] Dan McCafferty, Janis Joplin, Michael Jackson, Elton John, Roger Daltrey, Don Henley, [Electric Light Orchestra frontman] Jeff Lynne, Johnny Cash, Frank Sinatra, [jazz singer] Jimmy Scott, Etta James, Fiona Apple, [Pretenders frontwoman] Chrissie Hynde, Stevie Wonder, James Brown and a ton of others (predominantly Seventies rock singers) and would rather hear any of them anytime rather than me!"
Beagleit is complete idiocy to equate vocal range with "greatness" it helps to have a wide range to be a "great" singer, but saying that the vocalist with the widest range is THE greatest singer is poppycock!
