I am going to take a wild guess here: “Stairway To Heaven” by Zep is still # 2. # 1 is one of the group, “The Rolling Stones” hits, right? ;-)
It was about 10 years ago that Rolling Stone chose a ‘junk’ song like “I Can’t Get No Satisfaction” over Zep. What hypocrisy! They did so because they ‘stole’ their name from the group.
