Grand Funk Railroad, sometimes shortened as Grand Funk, is an American rock band popular during the 1970s, when they toured extensively and played to packed arenas worldwide.
 David Fricke of "Rolling Stone" magazine once said, "You cannot talk about rock in the 1970s without talking about Grand Funk Railroad!"
 Known for their crowd-pleasing arena rock style, the band was well-regarded by audiences despite a relative lack of critical acclaim.
 The band's name is a play on words of the Grand Trunk Western Railroad, a line that ran through the band's home town of Flint, Michigan.
Max Carl Gronenthal (born January 29, 1950) is an American rock singer, keyboardist, guitarist and songwriter.
 He is the current co-lead singer of the classic rock band Grand Funk Railroad.
 In addition, he spent several years as the keyboardist and lead singer for the southern rock band 38 Special, for whom he co-wrote and sang lead on the hit song "Second Chance".
Phoenix is the sixth studio album by the rock band Grand Funk Railroad.

Mark, Don & Terry 1966–67 is a 1972 2-LP set compilation album by the American garage rock band Terry Knight and the Pack released on ABKCO Records in an effort to cash in on the March 1972 Capitol Records album "" by Grand Funk Railroad.
 The album has a plain blue cover with lettering similar to that of the plain black cover of the earlier Grand Funk Railroad release.
 Mark Farner and Don Brewer from Grand Funk had been in Terry Knight and The Pack with Terry Knight, who then managed them until 1972.
 Knight also managed the Ft. Worth Texas group Bloodrock until mid 1971.
All the Girls in the World Beware!!!

 The first single from the album, "Some Kind of Wonderful", was released on December 16, 1974 and its follow-up, "Bad Time", was released on March 24, 1975.

Grand Funk is Grand Funk Railroad's second studio album and was released in December 1969 by Capitol Records.
 It was produced by Terry Knight and engineered by Ken Hamann.
 This release (aka The Red Album) was certified by RIAA with a gold record award, the first for the group.
 It includes a cover of The Animals' "Inside Looking Out" which is still a cornerstone of the band's live concerts today.
 Other key tracks include "Got This Thing on the Move", "In Need", and "Paranoid".
 The inside spread photograph of the trio, for the original album release, was used for the now infamous, $100,000, block-long and several stories high, New York City's Times Square billboard ad for the album "Closer to Home" (1970).
 The producers sought to achieve a concentration on Mark Farner's guitar, in response to the imbalance the band achieved in their debut album "On Time" (1969) with the prominence of Mel Schacher's bass.
Grand Funk Lives is the 12th studio album by Grand Funk Railroad.
 It was their first album since disbanding in 1976.
 Although known as a reunion album, it did not feature bassist Mel Schacher or keyboard player Craig Frost.

E Pluribus Funk is Grand Funk Railroad's fifth studio album and was released in November 1971 by Capitol Records.
 Like previous Grand Funk Railroad albums, it was recorded at Cleveland Recording Company and is the final album produced by Terry Knight.
 The title is a play on the former motto of the US government, E pluribus unum.
 The original release cover (designed by Ernie Cefalu) was completely round and covered with a silver-like film to resemble a large coin.
 The back side of the cover of this album included a die cast picture of Shea Stadium to celebrate Grand Funk beating The Beatles' Shea Stadium attendance record by selling out in just 72 hours.
