A few cover song related notes:
I've never been to another sporting venue that plays so many cover versions (especially ones that sound like they were recorded by a local garage band).
On the subject of Proud Mary, I once heard someone in the next booth over at a restaurant complaining about the restaurant playing the CCR version of the song, wondering "Why can't they platy the original by Ike and Tina Turner?".
The two common cover song choices that anger me are the Billy Idol version of Mony, Mony over Tommy James and the Shondells and the punk rock version of Ring of Fire (Social Distortion, IIRC) over Johnny Cash.
