Watch Bradley Cooper play a mean air guitar on 'Fallon'

Well it seems like Jimmy Fallon plans to spend 2015 much the same way he spent 2014: Getting celebrities to do the most delightful things for our entertainment. This time he gets Bradley Cooper to show off his mad air guitar skills to the tune of Neil Young's Down by the River. Cooper shreds it, we mean shreds it, while wearing the world's greatest wig. Clearly we've all been doing air guitar wrong our whole lives.
