They first used the name Klits, but were renamed Groep 1850 in 1966 when their debut single, "Misty Night" / "Look Around", appeared on the tiny Yep label. Though few copies were pressed, it established them as one of The Netherlands most original bands (alongside the Outsiders and Q65) and they soon signed to Philips. More singles ensued, in a highly psychedelic vein, including the "Mother No Head", their only single to chart on the Dutch Top 40.
