Paul Is Dead? The Beatles on youtube. Something bothers me about Paul

I was watching The Beatles on youtube.

One was an interview of Paul in the very early years.

The other was "Hello Goodbye".

In the interview, Paul has a very masculine, square cut jaw and thick lips and mickey mouse eyebrows.

In the later, Sgt. Pepper video of Hello Goodbye, his chin looks weaker, his lips look thinner and his eye brows are not nearly as pronounced.

The song freaks me out, like it's saying Goodbye to the real Paul and Hello to the new Paul. And Paul's guitar in the Hello Goodbye video has a red splatter graphic on it like blood.

The John Lennon looks at back and forth into the camera at Ringo as if he's thinking "that's the real Ringo, isn't it?", like he's joking about who else might have replaced.

Aaahh!!! This Paul thing is freaking me out!
