I am new to the list also. I am an American in New Jersey. I will quote
some sources. Simon and Garfunkel isn't OLD. I have some of their records
so I will check the jacket. Here is a repository of OLD music here in
America. It is public domain and you can print it.

Good luck hunting! I thought Paul Simon wrote the song. Ask him!
