Legendary all-American frontman and guitarist Mark Farner was the engine that repeatedly pulled the original Grand Funk Railroad to the top of the charts, and today he’s a platinum recording artist 30 times over. At age 70, Farner commands the stage with the same intensity and outpouring of love as he did in 1969, and his fans are still flocking to see “the Captain.” His epic hits defined a generation — from “I’m Your Captain (Closer to Home)” to “We’re An American Band,” along with covers of “The Loco-Motion” and “Some Kind of Wonderful.”
