I've got a couple questions about Paul Mccartney. Did he use a pick? or finger style? And since alot of the greatest of beatles tracks were after they were done touring, and they had no need to play any songs live, did he write his basslines before or after his vocals? Whenever I listen to beatles tracks i try to break down just how they came up with what they did, (although they might have been on some wild drugs when doing so). The second question may not be possible to answer, but I'm sure most of you know the second one.
