Before the recent passing of Teddy Pendergrass this song always struck a cord with me.  I remember hearing it for the first time as a teenager and almost breaking down into tears (you know how moody teens can be).  THIS is what's missing in today's r&b, those gut wrenching lyrics that span generations, that high note that seems to ease every pain in your soul, that emotional connection; the feeling that this one song couldn't have been made with anyone else in mind but YOU.  That's what 60's and 70's music represent to me; soul, passion and simplicity.
