One thing that I think is often overlooked when talking about Paul is what an incredible singer he is/was. He's such an iconic figure that people seem to hardly listen to what he actually did. I personally don't know many singer with a range going from Helter Skelter which would give any hard rock singer a run for his money, over song like I will or Here, There and Everywhere, to his cover of Long Tall Sally or Martha my Dear. The sheer power, flexibility and versatility of his voice is simply incredible. He really makes a beautiful sound.
Agree. He is incredibly versatile and very convincing in all of his modes.
And in response to your reply above, yes Paul has many other great bits. The bass on Rain, the acoustic guitar in Blackbird, the melody for the piccolo trumpet on Penny Lane...
