Since this was Bardic Madness XXI, I thought I'd go with the magic numbers theme and prove that LXII is the answer to life, the universe, and everything. Kudrun explained some of the significance of numbers, with reference to Aristotle, Augustine, Plato, Fibonacci and Boethius. Of particular importance for this event was Pythagoras's observation that all musical harmonies could be expressed in simple ratios.
Bardic Madness is probably the only event I'd travel 700 miles (each way) for a one-day event -- it was worth it. Thank you, Schattentor.
