He was (allegedly) 12 1/2 when BS came out Feb’74. He didn’t need any ID, just an adult claiming to be his parent or guardian.
That confirms the 12.5 years of age when BS was released but not knowing when he actually saw it, if he really did, the age would have been older than the 10 years of age he recited in the presentation Sunday.
Maybe, he was just excited or, as usual, lying for effect.
It is also probably Bush's fault that the TelePrompter was not correct, in the final analysis.
