Seeing Woz hold solder in his teeth while working really made my day. I still recall the form I had to sign in an early Electrical Engineering class that made me promise not to do exactly that. :)
Leaded solder is still easily available over the counter in electronic shops, and is the stuff of choice for manual construction, repair and rework by everyone who has half a clue.
There are numerous exemptions in RoHS on the requirement for lead-free. This is because everyone knows that lead-free solder is unreliable junk, and the risk is not acceptable in some applications.
If he's enough of an old-timer, it's probably still lead solder. I hear it was pretty hard to let go of, as lead solder is superior in virtually every way except toxicity.
