VKingOfTheWorldV sent this in to follow up on a report yesterday:

I read the post about Cubs and Punk/Cena of WWE. However it’s not WGN that schedules who throws out 1st pitch and sings 7th inning stretch as it’s Cubs call who does what. Normally people are booked in advance and George Lopez and other comedians have a show in Chicago which is probably why he is doing 7th inning stretch. Im sure if it was WGN’s call they would have the wrestlers sing the stretch but Cubs have the call who sings and who doesn’t.
