I used to believe that singers and musicians performed their studio recordings completely "live": they'd step into the studio, play and sing (while the next band was already in the waiting room), and got out 40 minutes later. I used to think this had to be stressful. Further more, I was wondering how that was possible when you sometimes hear the singer starting a new melody while he's still finishing the previous line.
