It was Bob Seger, not Pete Seeger, who cowrote Heartache Tonight.
I would like to see a song which featured each of the 4 guys on lead vocals originally. (Hotel California, Take It Easy, In The City, and I Can't Tell You Why for example. Though, I would prefer New Kid in Town, Already Gone or Heartache Tonight over Take It Easy). I think that would be a fair way to honor all 4 guys.
