There was a record that was put out in Baltimore for the Orioles. It might have been on that. sounds like the same kind of content. It was in 1961. Because they had a slogan to go with it "It can be done in 61". They (the Orioles) were faltering were trying to build up fan interest with it. Some lyrics I remember from it include: 'We're gonna win, Birds, we're gonna win! We're gonna win today. We're gonna win Birds, we're gonna win. We're going all the way . . .etc.
There was one about the Detroit Tigers: "Tigers, Tigers shining bright In the ball parks of the night. Your pitching's fair, your field adroit So why no Pennants for Detroit?
