I happened across this video that includes both Tom Petty and Prince performing a tribute to George Harrison.
It is a great clip, but brings a mixture of enjoyment of the music and sadness about the people. George Harrison passing was such a loss to the music world. And now there it the awful link between Tom Petty and Prince that they both died of drug overdoses, of which misuse of Fentanyl contributed. That drug has its place in pain management (cancer, etc), but it can be so deadly if misused or combined incorrectly.

The video is great. Watch till the end when Prince takes charge of his guitar!
