According to snopes, this is not true:

While Billy was present at his son Franklin's crusade, and he did speak on the final night, there is no truth to the story that he led by motorized scooter the audience assembled in the arena. A nice story, but not true. Snopes is a good place to check out those "urban legends" before passing them along as truth.
