The Official Blues Brothers Revival—the third “tour de Fort” concert of the 2007-08 season—got the crowd singing along at the Townshend Theatre last Thursday night with their homage to blues, gospel, and traditional soul music. “Elwood Blues,” left, and his brother, “Jake,” also got some audience members on stage to “shake their tail feathers” and even wished tour de Fort director Kerri Zucchiatti a happy 40th birthday. The fourth concert of the season—tenor trio “Romanza”—will perform here Nov. 29.
