This might be the video you're thinking of. The legendary Bob Hoover pouring iced tea while performing a roll (you can click forward to 2:07 to see the roll but the whole film is really interesting).
Apprehension is normal, Peter don't sweat it. It's a natural safety mechanism. As you get more experience you'll feel better. It's a whole, wonderful, new world up there so don't be surprised that it takes you a bit of time to get your confidence up.
Putting it another way, would you have felt confident tearing through the hills riding a motorbike at high speed with only a few hours on a bike under your belt? Would you consider a rider that behaved like that to be responsible and properly cautious?
With flying it's the same: experience builds confidence. Stalls and the like are a new thing to you, but as you gain experience and develop your skills, your confidence will also grow.
The trick is to make sure the confidence doesn't grow faster than the skills. THAT is what will get you into trouble!
You'll be right mate
