"I can see clearly now the rain is gone / I can see all obstacles in my way / Gone are the dark clouds that had me blind / It's gonna be a bright / Bright sunshiny day"
I Can See Clearly Now was written by the Houston-born singer-songwriter Johnny Nash. First released in 1972, it became a huge hit and the song has been covered by hundreds of artists, from the Jamaican singer Jimmy Cliff to the Irish rock group Hothouse Flowers.
For recording engineer and producer Luke DeLalio the original of the song is 'a masterpiece', with a sublime vocal performance and an arrangement that is surprisingly experimental for such an apparently simple song. Professor Kathy M. Newman of Carnegie Mellon University tells us about Johnny Nash's life and career, from his early years as a clean-cut crooner and teen idol, to his time recording in Jamaica and his later years, living on a ranch in Texas.
For author and psychologist Peggy DeLong it's a song of hope, resilience and love. It was once meant to be her wedding song but took on new significance after she lost her fiancé as a young woman in the 1990s.
The song appeared in Brenda Drumm's life when she needed it most. In a moment of darkness and worry, it came on the radio as she was driving home from a day of tests at the hospital near her home in County Kildare. It allowed her to dare to plan for the future.
Poet Jack Mapanje was detained in Malawi’s notorious Mikuyu Prison without charge from 1987 until 1991, under Hastings Banda's regime. He remembers singing the song when other political prisoners were released - "it's a song of hope".
And the author Joanne Harris talks about the song's "sense of perpetual sky" and how the lyrics provide grounding and comfort in troubled times.
