Wiegersma soon got a job as a set designer through Sonneveld. He gave up his studies, but he was now able to support himself. He wrote a number of songs for Sonneveld's first solo program in 1964. After this, Wiegersma wrote more lyrics, such as the song of the street singer Nickel Nelis, modeled after Copper Ko ("She couldn't resist beckoning") and the musical The Little Parade. Also for others, such as Leen Jongewaarden Willy Alberti. Wiegersma used the pseudonym for this Hugo Verhage.
He also made a number of paintings, and in 1970 he had an exhibition in New York. Wiegersma and Sonneveld now lived in Roquefort-les-Pins in the south of France. Sonneveld died of a heart attack on 8 March 1974 during a short visit to the Netherlands.
Wiegersma continued to write songs, among other things Again and again for the film Rooie Sien. He also found a new partner, the 25 years younger grand artist Hans van der Woude, whom he married on July 31, 2001.
Although he saw himself primarily as a painter, he also continued to be asked as a copywriter. In 2000 his texts were bundled with their history in the book Again and again the village, named after two of his songs: Again and again (played by Willeke Alberti) and The village (by Wim Sonneveld). This latter song, a text by him under one of his pseudonyms, Hugo Verhage to the music of Jean Ferrat (The mountain), is a reflection of the emotion at the reunion of Deurne, damaged by progress. On May 11, 2008, the path next to his family home was officially named My father's garden path.
From May 2006 there was a retrospective exhibition of Friso's paintings in Amstelveen. Wiegersma died at the age of more than 80 from the effects of lymph node cancer.
