The Doobie Brothers reunited with Michael McDonald on The Tonight Show starring Jimmy Fallon on Thursday.
The pairing performed a medley of a pair of classics, “Long Train Runnin’” and “Takin’ It To The Streets”, on the program and recorded a web exclusive take on their 1979 No. 1 US hit, “What A Fool Believes.”
A former member of Steely Dan, McDonald joined The Doobie Brothers in 1975 and his distinctive vocals were a defining part of the group’s biggest hits.
McDonald has occasionally performed with his former band in concert and appeared on 2014’s “Southbound” album, which saw the group joined by a series of special guests to duet on re-recorded versions of some of their classic tracks.
The Doobie Brothers are currently playing dates across the US with Gregg Allman and a variety of guest openers.
McDonald is performing solo US shows through to the end of the year following a co-headlining tour with Toto.
