I listened to my isolated tracks from A Day In The Life again yesterday, and without a doubt I can say it was indeed Paul.
I tried to post the files to where I post pictures but they would't accept anything over 200k, and after I pared them down it wouldn't accept anything that wasn't a picture.
So I have the files. Maybe someone here has a site that could host these, so everyone can hear for themselves?
But anyway, it is definitely Paul.
