Why Didn't Anyone List John Lennon & Paul McCartney As Singers With Large Vocal Ranges?

I'm really surprised that nobody even mentioned John Lennon and Paul McCartney as singers with large vocal ranges! As The All Music Guide Says Not Only Were The Beatles The Greatest and Most Influential Act Of The Rock Era, And Introduced More Innovations Into Popular Music Than Any Other Rock Band Of The 20th Century,But They Also Say As Singers John Lennon & Paul McCartney Were Among The Best And Most Expressive In Rock The Group Harmonies Were Untricate & Exhilarating! And John Lennon had a very unique beautiful voice and both John and Paul had great love song and great rock singing voices. And Paul McCartney had a great vocal range going from a love song to a rocker voice often in the same song!
