Watch Bradley Cooper perform Neil Young's "Down By The River" on air guitar

He also rocked out immensely, showing off his air guitar chops by strumming along to the lengthy guitar solo in Neil Young's "Down By The River". Cooper's many things - a great actor, writer and producer - and it turns out that he's also a proficient air guitarist, after honing his skills as a child.

He performs across the stage, and in the audience, with Fallon and house band The Roots in awe.

See if you can follow along with his razor-sharp moves.
