Paul Simon and Art Garfunkel were delivering in the 70th some sensible pop songs as guitarists singers team.

Most important tunes :

Scarborough fair / Canticle,
Sound of Silence,
Bridge over troubled water,
El condor pasa ( If I could ) ,
Mrs. Robinson,
Cecilia

O.F.D this list is stimll incomplete.If you like music like El condor Pasa as far as I know actually based on a peruan historical song the you should have a look to my site www.o-f-d.de.There im playlist THE WORLD you’l find the composing work of mine PERUAN SHERPAS.Its equal or better and purely bymyself but in Peruan hit style.
