Paul's "natural" voice vs. his "forced" voice | Fab Forum | The Beatles Bible

I’ve noticed this about Paul.  There are so many songs where, when he’s called on to improvise vocalisms (including screams, but also other creative things he does to amplify portions of the song) and he does so in an effortlessly inspired manner.  Then there are songs where it seems clearly forced and doesn’t quite work.

One example for now:

With a Little Luck — natural vocalisms that work

That Was Me — at certain key points, it sounds forced and kind of doesn’t work for me
