Grand Funk Railroad
Grand Funk Railroad is an American rock band that was very popular throughout the 1970s. Formed in 1969 by Mark Farner (vocals, guitar), Don Brewer (drums) and Mel Schacher (bass). Craig Frost (keyboards) was later recruited around 1972. Grand Funk Railroad has sold in excess of 25 million records to this date, 10 million of which were in 1970 alone. They were a top concert draw and often cited as "the loudest rock and roll band in the world."
