Unit 4 + 2 were a British pop band, who had a number one hit in the UK Singles Chart in 1965 with the song "Concrete and Clay". The track topped the UK chart for one week.
In 1962, Brian Parker, then the guitar player and songwriter with The Hunters, decided to form his own vocal harmony group. He asked his friend David 'Buster' Meikle to join him. They asked singer Tommy Moeller and Peter Moules, who were at school together, to join their group which they called Unit 4.
