Original Bay City Rollers frontman Nobby Clark claims he was the main voice on the Edinburgh band's biggest US hit.
Clark has vowed to recover decades worth of royalties having been the voice of the band for almost a decade before being replaced by the late Les McKeown, who died in 2021.
As the Record reports, Nobby claims it was his voice on the single that broke the band in the US - Saturday night. He also claims he was conned out of cash by Rollers manager Tam Paton, who has also passed away.
