vivazappa ..*ahem* so what is wrong with it being a Warren Zevon song?  He had a lot of good songs. Not his fault the public latched onto Werewolf and ignored the rest of his catalog. Yes, I'm a big fan of WZ. :)
Linda R also covered his <i>Hasten Down the Wind</i> which has nice B3 possibilities. 
But, if Grace were to cover a cover, my vote is still for Tumbling Dice. 

Jackie, I also hope something is done to recognize Linda Ronstadt's place in our musical history. There have been scattered mentions of her being added to the R&amp;RHoF in the past, perhaps this will cause a full out campaign for her. The selections have been criticized for both the low number of women and Latino artist inductees. That could give the selection committee an added (and unstated) incentive to add her to the next round.
