Point of order!
I consider myself well-versed in all things Zeppelin and have never seen this accusation thrown at John Bonham. Do not unfairly tarnish this legend.
To slightly hijack my own reply, if you ever get a chance to see Jason Bonham and his Zeppelin cover band, do it! I’m blown away each time I see him.
