What is Robson Green famous for — his acting or his singing?

Robson Green is famous for both, though he first gained widespread recognition through his acting. He became a household name in the UK through his role in the television drama Soldier Soldier in the early 1990s, and went on to star in many popular series including Wire in the Blood and Grantchester. However, his singing career also brought him enormous commercial success. Together with his Soldier Soldier co-star Jerome Flynn, he recorded several singles that became massive hits in the UK, including Unchained Melody and I Believe, which both reached number one. Their pop success was somewhat unexpected given their acting backgrounds, and the duo sold millions of records during the mid-1990s. So while he has maintained a long and respected acting career that has arguably been more sustained and critically regarded, many people in the UK remember him just as vividly for those chart-topping pop hits with Jerome Flynn. He is genuinely well known for both aspects of his career.
