I went to the 2nd game of the World Series that year, Jack Sanford pitched a shutout, McCovey hit a home run for 2-0 victory over the Yanks. Get this though, my brother's best friend sat next to me, a fellow who was to later figure in the Giants two worst trades...Frank Duffy! (Duffy also played in the Bucky Dent game for the Sox)
We lived in the Central Valley and everyone carried around a transistor radio, was crazy about the Giants. My father & grandfather grew up in New York State, and had been Giants fans going back to John McGraw/Christy Matthewson (Lefty O'Doul was sort of the Cody Ross of the '33 Giants, and my Dad's boyhood hero). I remember the games you describe. The third game, we thought the Giants had lost, went out dejectedly to play (I was only 7), then an older brother came out screaming "We won!! We won!!"
I saw Mays' last game (the 7th game of the '73 A's-Mets), apparently he was on-deck when the last out was made, just as he was on-deck when Thompson hit his homer. We went to McCovey's funeral at ATT, I wept for three days. Drysdale was a headhunter (aimed at both Willie's heads on first pitch), so we didn't like him. Funny that Perry pitched in '62, his rookie season. We went to game in '68 the day men landed on the moon, then watched Perry hit a homer (his first). The next day, one of the players said "that's so weird, because when Al Dark watched Perry taking BP in '62, he shook his head and said 'they'll land men on the moon before Perry hits a home run!'"
