An anagram for the Goldring twins' surname, Londoners' Colin and Stewart formed Gnidrolog in 1969. Joining them was bassist Peter "Mars" Cowling and drummer Nigel Pegrum, the latter having been in the pre-Uriah Heep band Spice. Gnidrolog toured extensively, supporting numerous progressive acts, as evidenced on dozens of concert bills from the era; Colin, most famously, added recorder to Yes' "Your Move" from The Yes Album. Signing to RCA records, the band released the dreadfully titled In Spite Of Harry's Toenail in early 1972.
