Paul McCartney doesn't have to do much to dominate any stage he's performing on.
But the rocker called on the assistance of Dave Grohl Saturday night to help him perform The Beatles classic I Saw Her Standing There!
The music legend was performing at the O2 Arena in London when the Foo Fighters frontman joined him on stage and grabbed a guitar to join in — and he totally rocked out like a teenager!
This isn't the first time McCartney allowed Grohl to perform this 1963 hit with him. They sang the tune together at the 2009 Grammy Awards!
Check out the fan footage (below) to see the duo rocking out on stage!
