It was released on December 29, 1969, by Capitol Records, just four months after their debut album On Time.

It includes a cover of the Animals' 1966 song "Inside Looking Out", which is still a staple of the band's live concerts.

Grand Funk was originally released by Capitol Records in LP, cassette, 8-track tape, and reel-to-reel configurations.

The edits on these songs reduce the album's overall running time by approximately five minutes.

Also included is a pair of Shinin' On 3-D glasses, a guitar pick and a sticker reproducing a concert ticket.
