Watch: Run the Jewels bring 'Legend Has It' to Fallon

Run the Jewels celebrate St. Paddys Day by bringing some underground luck to The Tonight Show

On St. Patrick's Day, Run the Jewels performed RTJ3's "Legend Has It" on The Tonight Show with Jimmy Fallon.

In the duo's first time back to the NBC airwaves since their "Nobody Speak" performance with DJ Shadow on Fallon last summer, El-P and Killer Mike fully embraced the holiday's motif with shamrock-green lights and El-P signature red cap being replaced by a green one.

As far as great television performances go, Friday's "Legend Has It" might be remembered as a landmark moment for the group as the entire Tonight Show crowd took to their feet and chanted "R-T-J!"

Concluding with Mike and El-P giving Jimmy a green St. Paddy's themed-RTJ shirt, revisiting the clip is just the leftover luck we needed to start the week off right.
