I have noticed this when I goto to Braves game: the organist plays songs that either (a) make fun of the opposing team's batter or (b) somehow relates to the batter's name.
For example, from Saturday's game:
Danny Espinosa- "Danny Boy" (self explanatory)
John Lannan - "Hey Jude" (John Lennon, John Lannan)
Rick Ankiel - "Never Gonna Give You Up" by Rick Astley (rickankielrolling)
Ian Desmond - "Ob-la-di, Ob-la-da" (from the lyric"Desmond has a barrow in the marketplace...")
Jayson Werth - "Jesus is Just Alright" (because of his facial hair. They have also in the past played "Werewolves of London"). Also "For What It's Worth" (Worth. Werth.)
And the biggest stretch of all:
Wilson Ramos - "Crazy on You" by Heart. The connection here is that the lead musicians are the Wilson sisters.
Anyone else notice this?
