I'm more direct: u2santos. Anyone can find me if he knows the band I love plus my surname haha. And yes, The Beatles still did covers sometimes, both in the first albums and live. They didn't transform the musical industry in a week. It took them several years. BUT they did it, and what has been the music businness from 1970 to a few years ago (internet has been the next great revolution after the Fab Four stopped making music) was mainly their merit (fault?
).
For what is worth (and relevant to the discussion), The Zeps followed Beatles steps in many ways.
