The Doobie Brothers have tagged 13 new fall dates on to their itinerary, which already includes a pair of opening slots for the Eagles in California and two full-album gigs in New York City. The Doobies -- led by co-founders Tom Johnston and Patrick Simmons along with longtime member John McFee -- said in a press release announcing the new stops: "We will be writing and recording new music this summer, and we are looking forward to heading back on the road in September. We will start the fall tour with a couple dates with the Eagles and the Zac Brown Band, and we will end with two incredible, full-album performances at the Beacon Theatre in New York City in November."

Guitarist Pat Simmons told us that it's radio -- above all other pockets of the industry -- that deserves the credit in keeping the Doobies front and center for the fans: "Thank goodness for, y’know, classic (rock) radio, really, I mean that’s probably why a lot of people still know who we are and what we’re doing."
