uh. just listen to it i guess. chord tabs dont tell you how many times, just when to change. plus it shouldnt be that hard to figure out.

listen to the record, really. most chord charts dont tell you the specific amount of times to play each chord. luckily bad moon rising is done nearly all in up-down two chord swipes (DD DD AA GG DD etc). and just a word, the song was actually recorded in E tuned down a step.
