Paul is one of the greatest songwriters and performers alive as well as a fine musician. This was an excellent lesson in songwriting and how they did it back then. Only difference being George Martin was there in the early days with a couple of other engineers using tape machines instead of a computer when they did first drafts of new song ideas. Of course the completed song wasn't fleshed out in less than five minutes. He wasn't there for a concert or a band reunion or to record his latest single on the fly. I loved it.
Thanks Trax.
