A couple of points: First, I too remember hearing a radio interview with Ben E King wherein Ben E was talking about his "street corner" singing days, and he cited " Speedo" as his all-time favourite doo-wop recording. Secondly, are our American friends familiar with " Only You" ( not The Platters' song) by the British group "The Flying Pickets" ? If not, try to hear it. It really is a beautiful piece of doo-wopish/acapella singing.
