The Doobie Brothers brought a piece of their past with them when they visited The Tonight Show Starring Jimmy Fallon last night.

The group was joined by former member and five-time Grammy winner Michael McDonald, whose tenure with the Doobies produced a string of hit records that included 1978's wildly popular Minute by Minute LP. Their Tonight Show set found McDonald sitting in for a medley of “Long Train Coming” and “Takin' It to the Streets” as well as a performance of the smash Minute single "What a Fool Believes" that didn't make it onto the show, but is presented above as a web-only exclusive.

Although McDonald departed the lineup when the Doobies dissolved in the early '80s and didn't return for their eventual reunion, he's remained in the group's orbit over the years, periodically performing live with them and acting as a special guest for various projects — including last year's Southbound, which united the band with an array of bestselling country acts for re-recordings of Doobie Brothers classics.

The band is currently in the middle of a run of tour dates that includes shows with Gregg Allman and the Steve Miller Band. McDonald, meanwhile, recently embarked on a batch of solo dates following his co-headlining tour with Toto and will be on the road through the end of the year, when he wraps up 2015 with a special Christmas tour.
