Hopkins re-recorded the closing track, "Edward", on his solo album The Tin Man Was a Dreamer, which features members of the Rolling Stones and the Beatles. (“Edward” was a nickname for Nicky Hopkins, made up by Brian Jones during a 1967 session at Olympic Studios in London. The story goes that Jones was tuning his guitar and asked Hopkins to give him an E on the piano; with other noise interfering and Nicky unable to hear what he was saying, Brian eventually shouted out: "Give me an E, like in Edward!") "Joseph's Coat", co-written by John Cipollina and Nick Gravenites, also appears on Big Brother and the Holding Company's album Be a Brother, which featured Gravenites on vocals.
Original guitarist Gary Duncan does not appear on this album, having quit the band for a time.
In his review of the album, for AllMusic, Lindsay Planer writes: "This somewhat uneven effort would sadly foreshadow QMS's journey from psychedelia and into a much more pop-oriented sound on their follow-up, Just for Love (1970). However, enthusiasts of those albums will find much more to revisit on Shady Grove than those who favored the first two records."
