Their production line of pop created a string of Eighties chart-toppers for Kylie Minogue, Rick Astley and Bananarama. But even a celebratory Hyde Park concert has failed to persuade the sundered partnership of Stock, Aitken and Waterman to share a stage when the stars they created entertain 50,000 fans.
Pete Waterman the producer-turned-talent-show judge, will whip up the crowds at Wednesday's Hit Factory Live show, which promises to restore former teen idols Brother Beyond, Sonia and Dead or Alive to the limelight. Minogue and Jason Donovan have agreed to recreate their 1988 duet, "Especially For You".
While the Stone Roses set aside ancient feuds to re-form, Waterman says the show will go on without his former partners, Mike Stock and Matt Aitken. Their musical partnership, which produced 100 top 40 singles, generating £60m, ended 13 years ago with Stock and Aitken launching a failed legal action against Waterman for substantial royalties which they claimed they were owed. "I don't think they're even turning up," Waterman, 65, told The Independent.
"It's still a tribute to all of us but it's a celebration of PWL [Waterman's production company which housed their star stable] and I'll be there. I'll be sad not to see Matt and Mike, but it's up to them."
Waterman said he climbed greater heights after breaking with his partners, through Steps, the late 90s quintet he styled as "Abba on speed", who will headline at Hyde Park. "When we packed up I went on with Steps and it's hard to believe but they were the biggest act I ever had. They did a record 26 nights at Wembley Arena."
Stock, who once called Waterman "a buffoon" who "thinks talent is blonde hair and big tits", issued a statement through his office, which read: "Unfortunately, Mr Stock cannot attend the concert on 11 July." Aitken could not be reached.
Waterman generously describes his former colleagues, who created the musical backing for the hits, as "the biggest part, the most talented" elements of their mini-Motown.
The duo are missing out on an event which Waterman believes provides cultural vindication for the studio-manufactured disco-pop.
"Our music was female dominated," Waterman said. "This was actually the music of a generation and for some people it was a very important part of their lives."
