The first U.S. issue of the album was on the Dunhill Records division of ABC Records. It featured a revised cover with a white background instead of purple. The mid-priced "Charisma Classics" re-issue from the early 1980s had a blue cover. A re-mastered version of this album added bonus tracks and was released in 2005. One of the additions is a studio version of "Squid / Octopus", a song that had been a staple of early Van der Graaf Generator concerts.
