In the 70s though, if you were a "serious" rock band you didn't really do singles. Your audience were all album buyers. ...
And I thought that Led Zeppelin had a strict no singles policy?

I thought as you did on both these, but look at the number of singles Sabbath, Floyd, Zep, and Genesis released. Zep released 15 singles. And Jethro Tull released 33, with two making it into the top 40 (in fact the top 20).
