Tourmates Brian Wilson and Jeff Beck dropped by Jimmy Fallon's late-night TV show last night and performed a pair of songs together.

The brains behind the Beach Boys and the guitar god launched a tour together in Florida on Sept. 27. The month-long road trip continues through the end of this month. This week they played the New York area, so they stopped by 'Late Night With Jimmy Fallon' yesterday for a performance.

Backed by a full band, including fellow Beach Boys Al Jardine and David Marks, Wilson and Beck performed the Beach Boys' 'Smile' track 'Our Prayer' and the traditional 'Danny Boy.' You can watch video of the performance above.

It seemed like an odd choice to promote the duo's tour: 'Our Prayer' is basically a two-minute a cappella piece that sets up 'The Smile Sessions' box set as its opening track, and 'Danny Boy' featured a bunch of group harmonizing over Beck's fluid guitar solo.

But then again, these two have always done things their own way, and at the very least it should give fans a taste of what to expect from their tour.
