Singer

Holm's pre-Collins singing career began with a psychaedelic phase in the late 1960s before his high-pitched voice found its natural home doing Euro-pop. His best known song is "Monja" (aka "Monia" in the French version). Other songs included "Syster Jane" (a Swedish cover version of New World's "Sister Jane") and "You Will Be Mine."

Marriage

Holm married actress Joan Collins 6 November 1985. Collins sought an annulment in December 1986 and was granted a final divorce 24 August 1987. According to Collins, the marriage quickly degenerated into a string of "interminable arguments... and hearty crockery-throwing rows." She said Holm was a bully with a ferocious temper and "the most combative person I've ever met."

In December 1986, Collins received a restraining order against Holm. Undaunted, he gave poolside interviews (in leopard-skin briefs) blaming Collins's identification with her Dynasty character. "Joan is consumed by Alexis, that's why she's doing this. She really loves me and I love her and we'll get back together, I know it." He contested a pre-nuptial agreement, limiting him to 20 per cent of Collins's $5 million earnings during their 13 months together. Collins hired flamboyant divorce lawyer Marvin Mitchelson and the proceedings became a media circus.When Holm and his supporters picketed Collins' Beverly Hills house waving placards, he became a national punchline. David Letterman joked about Peter Holm's Top 10 Grievances Against Joan Collins, which included "No. 5. Wouldn't Support His Campaign for Presidency of 'Weaselly Gigolo Club'" and "No. 2. Somebody Finally Told Him What 'Parasite' Means."

At the trial, Mitchelson produced Holm's secret lover, an aspiring starlet called Romina Danielson, and grilled her so intensely she fainted on the stand, conveniently revealing her cleavage right by photographers.

Holm lost his case, collecting only $80,000 as agreed in the pre-nup. A New York radio station hosted a fundraiser for him and he retreated to Switzerland. Directly after her final court appearance Collins famously declared "I don't need a husband, what I need is a wife!"

Soon after the divorce, Holm inherited money of his own.

Collins gave her candid side of the break-up in Second Act, her second volume of memoirs, and subsequently referred to him only as "the Swede."
