I had never heard this about Zeppelin but I suppose supergroups were formed at younger ages than today. I think Plant and Bonham were only 20 when Zeppelin formed. But then again Clapton was only 21 when Cream formed and that was certainly a supergroup (and one that worked!). By the age of 21 many of these guys had a lot of years of experience in that era.
