Alanis Morissette performing "Dear Prudence" (October 2, 2001)

About two weeks after 9/11, there was a televised benefit concert celebrating John Lennon's work (you can check out the setlist here). Alanis Morissette performed a mind-blowing cover "Dear Prudence" that I have thought about for the last 25 years. She absolutely transformed that song (and I say that as a big Beatles fan).
