I like this. And I will bring the cookies.
Could he sing “American Pie”? The irony would be wonderful.
Another vote for Freddie Mercury.
How about Nick Drake - provided he doesn’t kill himself again, of course?
Just thought of another one: Benjamin Orr. I’d love to have a real reunion of The Cars.
Bless you, dear! 
Wasn’t Buddy Holly just the best?
I went to karaoke last night and sang “Every Day” (badly, no doubt!) in Buddy’s honor. Did you know that there were actually people there who didn’t know who did that song?
It really is very sad that Buddy Holly is dead. He just looked like such a sweet kid.
I agree with so many that already have multiple votes, so to be different, I would like to suggest
Ronnie Van Zant
Now, now, don’t throw anything at me! He was a hard-scrabble redneck to the bone, but damn he had the heart of a poet. I would love to see how his songwriting would have matured, especially considering he was beginning to grow up and ease up on the paryting when he was killed.
