Les McKeown's estranged Bay City Rollers pal Nobby Clark regretted not mending their feud.
Frontman Les died suddenly aged 65 at his home surrounded by his close family on Tuesday.
Now Nobby has sadly said the pair "missed out" on having a "better relationship" after they were locked in a feud.
The missing Bay City Rollers' millions was at the heart of their feud, Nobby revealed.
Originally Nobby fronted the band before Les stepped in to replace him.
He told The Daily Record : “Les and I had our differences and we had a confrontation in a court case in New York and it was a horrible situation where we should have all got together and we could have sorted it out.”
The New York court case involved a claim Arista Records failed to pay Bay City Rollers tens of millions of dollars in royalties for more than 30 years, The Daily Record reported.
Nobby said none of the band could agree and eventually it led to the demise of his relationship with Les.
He added: “We could have taken the record company on and there was a good chance we could have one if we had put something together collectively.
“There was so much in fighting and arguing and nobody could come to an agreement. It was very sad. Les and I could have had a much better relationship and its very sad now that opportunity has been missed.”
In a kind tribute, Nobby hailed the late legend as a "great performer and entertainer" who was "great with the fans on stage".
The musician revealed he was "absolutely in shock" over Les' sudden death.
Les' death was announced via the band's Facebook page with a statement from his family.
It read: "It is with profound sadness that we announce the death of our beloved husband and father Leslie Richard McKeown. Leslie died suddenly at home on Tuesday 20 April 2021.
"We are currently making arrangements for his funeral."
