They aren't all perfect and they don't have Ooby Doobie yet but they are a great start for someone who is looking for some licks.
Sometimes after getting an idea of where some licks are played, watching a performer play it helps you figure it out. Here's a clip of John playing Ooby Dooby at a Roy Orbison tribute show. It's helped me figure out some of the lead.
