The album cover art was done by Henry Cow roadie and sound mixer Maggie Thomas. She created it from a collage she made out of a cut-up Henry Cow poster she had designed a few months earlier.
In 1995, East Side Digital Records reissued Concerts as a double CD with four extra tracks. The extra tracks came from Greasy Truckers Live at Dingwalls Dance Hall (1973), a double LP of an October 1973 concert performed by Camel, Henry Cow, Global Village Trucking Company and Gong, each band contributing to one side of the double album. Henry Cow's contribution, however, was actually recorded a week later at The Manor Studios because a power failure at the event had delayed the start of the concert and a 2 am curfew reduced Henry Cow's set (billed last) to ten minutes. At the Manor, Henry Cow improvised their Greasy Truckers set to tape and mixed the tracks in a single session. An outtake from this recording session, "Bellycan" was released on the 1991 CD-release of Legend.
In October 2006, Recommended Records released a remastered version of Concerts, which included the Greasy Truckers set, on a double CD. The original dynamics of "Oslo" were restored, which had been compromised to fit it onto side three of the double LP. The remastering was done by Bob Drake in March 2006. An accompanying booklet included a 1977 interview with Henry Cow in Sweden, and a seven-day extract from the "November/December 1977 Road Diary" by Chris Cutler.
