From Create Your Own Story

You give your younger self some pointers on helping the past Marty before moving on. Marty calls you to say he got the Almanac. You start to fly the DeLorean to his position. Marty later calls again to say Biff's gang is about to jump his past self while he's singing Johnny B. Goode.
