Continuing the story of the Buddha's life through his awakening and his setting the wheel of the Dhamma in motion.
(Note: it is largely understood to have been a Brahma God, Sahampati, who asked the Buddha to teach--not a Brahmin as mentioned in the talk.)
The Buddha's childhood memory that led him to reject self-mortification, accept nourishment, and find the middle way. Samadhi, a true holiday. The story of Sona, and turning one's efforts in practice.
