"Sey Hey (Willie Mays Song)" by The Treniers

Willie Mays was arguably the greatest player in baseball history. And, as it turns out, he wasn't a half-bad back-up vocalist either. It's him you can hear answering the band in The Treniers' 1954 tribute to the Giants' center-fielder, which was conducted by what must have been a ridiculously young Quincy Jones.
