Charlie was living proof that you can have a band where everybody does drugs, alcohol, weird shit, groupies, weird timings, but as long as the drummer is rock solid you will still have a good band. If your drummer is steady as a rock you can build a musical house on it that looks like it came straight out of the imaginations of R. Giger or Tim Burton.
Mr, Watts, you allowed history to happen. You may not have been the flashiest or most technical of drummers, but without you history would have been different. And probably a little more bland. I salute you!
