The key players:
- Ann and Nancy Wilson, a.k.a. Heart. If you are too young to know who Heart is, listen to some of their music. They are among the greatest female rockers ever.
- Jason Bonham on drums - Jason is the son of John Bonham, the deceased drummer for Led Zeppelin
- Shane Fontayne on electric guitar - Nails the Jimmy Page solo
- The surviving members of Led Zeppelin; Jimmy Page, Robert Plant and John Paul Jones. Their reaction throughout this performance says it all

What makes this cover so good:
- Perfect acoustic guitar intro from Nancy Wilson
- Ann Wilson's vocals. She is both faithful to the original song yet somehow makes it sound like she could have been the one to make it famous in the first place
- Jason Bonham channeling his father
- Shane Fontayne doing Jimmy Page in front of Jimmy Page and with his obvious approval
- The John Bonham tribute chorus at the end
- The reaction of Led Zeppelin themselves. When you have Jimmy Page grinning from ear to ear and Robert Plant clearly emotional, you have nailed it!
