This is one of my favorite songs too, but I prefered "Don McLean" version. It's not as SWEET as Garfunkel's but has some DuWob accent to it and he hit high notes so accurate and pretty and raw.
Here it is;
BUT, BUT best of all (to my opinion) two thumps up from me to "Flash" and "Axl Roses". They tranformed this sweet one into the HEAVY ONE especially when Axl reached his signature scream backed up by Flash's Les Paul! can't get better than this!!!!!
