The technical curriculum of throws and locks is the only way to arrive at a definition of aikido that has any practical meaning at all, no matter what O Sensei says.
What he did, at least in the case of the dancer. Anyway, never mind the old man, he's dead anyway...
Of course the technical curriculum can be quite different in many cases - of Tohei, Shioda, Mochizuki, Tomiki, Nishio, Yamaguchi, Saito, Watanabe, Abe, et al - who is and isn't doing Aikido?
Some of would definitely say (or have said) that what you're doing isn't Aikido - of course, you might say the same thing...
