I would go for Macca because he just does it without any s***
i also love John & George's voices, but it always annoys me when i listen to
the double-tracking that Lennon did on his voice or the echo he had on it.
This is why i love john's home demo's when his voice is clear.
George had a beautiful tone to his voice, i've realised this in recent times, just listen
to Stuck Inside A Cloud.
But i voted Paul as he kind sing alsorts like rock n roll, love songs or the whimsical songs!
and on his new album he kind of showcases all sides to his voice, Mr Bellamy (funny whimsical voice),
Only Mama Knows, Nod Your Head (rock n roll voice) or You Tell Me (the soft macca voice!)
