Jack White was busy in Rhode Island this weekend.  The former White Stripe leader headlined the Newport Folk Festival on Saturday, and then hopped over to nearby Providence to crash Beck's encore later that night. 

After being introduced as the "best bartender in the world," White joined Beck on stage to play and sing background vocals for a pair of the singer's classics - "Loser" and "Pay No Mind."  Opening act Sean Lennon eventually came out as well for a medley of "Where It's At and "One Foot in the Grave." 

This isn't the first time Beck and White have joined forces.  Beck released a single on White's Third Man Records back in 2012, and White is set to appear on Beck's upcoming Song Reader album.
