When I was 6 or 7, I really liked the duet "Perhaps Love" by John Denver and Placido Domingo, just that at that time, I didn't know it was Denver and Domingo. I used to think a) it was 3 people singing and b) that those were the 3 knights from the "Neverending Story" by Michael Ende (which was also among my favorite books at that time). I always imagined how they would ride around all day fighting enemies and at night sit at the campfire to sing this song together. Those were the days. ;)
