John Bonham was good when led zep 1 came out. Then he was young and somewhat sober. Bonham could do his triplets properly and they sounded awesome. Later, when he got older and more famous and more drunken, his playing was horrible. Even in this video, you can see where he screwed up his triplets and tried to recovered but could not. If it were not for the fact that he was in Zeppelin, he would remembered as a mediocre drummer at best. Before anyone asks, Yes, I am a drummer and I know what I am listening to; and yes, he made many terrible mistakes; but it was overlooked; because....Zeppelin! Just my two cents.
