Such a great song it's hard to imagine a bad cover, and for me these are good, better, and best.

Frankie: 75. The song itself does the heavy lifting here, but the band doesn't mess it up.

Wolfsbane: 80. I've heard better metal covers of pop / rock songs, but they keep the energy going. The vocals aren't particularly engaging though.

Amy: 98. I was transfixed by what she did with her voice. The only one of the three that stands on its on, without the need to be compared to the original.
