Unit 4+2 was a one-hit wonder that probably deserved better. As one of the better acoustic-electric bands of the mid-'60s, the group stormed the charts with one memorable hit, "Concrete and Clay," scoring on both sides of the Atlantic, but they were never able to come up with a follow-up that was as catchy. The group originated with guitarist Brian Parker and an instrumental band from Hertfordshire called the Hunters, who recorded for the Fontana label in 1961. Parker left the Hunters in early 1962 and joined Adam Faith's backing band the Roulettes. He didn't stay long with the latter band, preferring to put together a group of his own with the emphasis on vocals. Parker recruited guitarists Tommy Moeller (with whom he began writing songs) and David Meikle, and singer Brian Moules, and the quartet played gigs at youth clubs and other local venues, and turned professional soon after.
