Any cover songs you think I should give a listen to? Name them in the comments and I'll download them and update the post with what I thought.

Edit: Here are the recommendations:

Donald recommends Jason and the Scorchers version of Ring of Fire
Sandy had two excellent recommendations with Boys of Summer by Ataris (original Eagles) and Baker Street by the Foo Fighters (original Gerry Rafferty)
Gooseneck recommended Hanky Panky by the Cramps (original Tommy James & the Shondells)
Donald came back to add Powderfinger by the Beat Farmer (original Neil Young) and Mule Skinner Blues by the Cramps
Rick from Toronto had a good call with Suspicious Minds by the Fine Young Cannibals (original Elvis) and Tom Jones and New Model Army doing Gimme Shelter (original Rolling Stones)
Me - I'd like to add the Black Betty cover by Tom Jones (you know he's intentionally campy)
Jeremy suggests Rusty Cage by Johnny Cash (original by Soundgarden)
