Actually Keith Moon played so fast that he was making a beat every 1/2 a millisecond whic, i believe is 1200 beats a minute. At the time a machine gun couldn't fire that fast.
where did u get this information? and those who gave you it, how did they get the information, i dont think they ever recorded what his BPM was. And if they slowed down a tape to determine it, then he would hold the record for fastest BPM, am i wrong?
