Suzi Quatro and Chris Norman are renowned musicians known for their collaborative work in the 1970s and 80s. Quatro, an American rock singer-songwriter, bass guitarist, and actor, brought a pioneering female presence to the male-dominated hard rock genre. Norman, the lead vocalist of British rock band Smokie, is recognized for his distinctive soft rock voice. Their most influential work as a duo is the 1978 hit single "Stumblin' In", which fuses Quatro's hard rock roots with Norman's soft rock style, and peaked at number 4 in the U.S. Billboard Hot 100 chart.
