Grand Funk Railroad

Grand Funk Railroad (also known as Grand Funk) is an American blues rock band that was highly popular during the 1970s. Grand Funk Railroad toured to packed arenas worldwide. A popular take on the band during its heyday was that, although the critics hated them, audiences loved them. The band's name is a play on words of the Grand Trunk Railroad, a railroad line that ran through the band's home town of Flint, Michigan.
