Yeah, although it may look like it was a simple question, yet..
i doubted two answers.
It was first at hand to say Paul Simon but the song is registered in
"my bible" (music-catalog, it's a huge book and when i need to look up stuff, i tell costumers i will need to have a look in my bible)
as being owned by Simon AND Garfunkel.
What did you guys fill in?
I'm curious...
