Michael McDonald revisited his Doobie Brothers years for the band's upcoming album of country-fied remakes. He tells he worked on "Takin' It to the Streets," "What a Fool Believes," and "You Belong to Me."

Sara Evans joins him on "What a Fool Believes," while Love and Theft appear on "Takin' It to the Streets." As for "You Belong to Me," which Carly Simon co-wrote and also recorded, McDonald would like the final mix to include contributions from Vince Gill and Amanda Sudano-Ramirez, the daughter of late Donna Summer, who is said to have a voice reminiscent of her mom.

But not everything has gone according to plan. McDonald says some of the Doobies' first or second choice guest stars weren't available when they began recording in Nashville. And the project is not quite a jam-session of the surviving or still-active Doobies. While McDonald says there was some interaction with his band-mates, he recorded many of his tracks by himself.

Still, he tells Billboard it was a positive experience. "We've all come away from the thing feeling much more of a camaraderie than anything. I could never be grateful enough to the Doobies for the opportunities the organization gave me over the years."
