are you sure it was chuck norris action jeans? LOL they stretched too hahaaSpeaking of bell bottoms, the closest I ever had to those were something called "Kickin' Jeans" in the early '80s. They were jeans specially designed so you could kick without tearing them. Basically, the crotch area was designed the same as gi pants. I got 'em thru Black Belt magazine (Bill "Superfoot" Wallace modeled them in the ad) and I wore them about a year or so. I'd almost forgotten about those!
Back OT:
If I listened to music during training again, it would definitely be '70s (classic rock).
