The Doobie Brothers is a band with almost twenty official members throughout its five decades of existence. But Tom Johnston and Pat Simmons have been playing guitar and performing vocals for the band since Day One. Tom and Pat talk with Marc about how their family-like band has grown and evolved throughout the years, particularly during iterations with members like Jeff “Skunk” Baxter and Michael McDonald. Also, during his time in Tulsa, Marc pays a visit to the new Bob Dylan Center and talks with its director, Steven Jenkins.
