Bucks Fizz may have been harmonious when they won the 1981 Eurovision song contest with Making Your Mind Up, but its members are now in dispute over who has the right to claim the group's name.
Three of the group, Cheryl Baker, Mike Nolan and Jay Aston, who have performed under the name the Original Bucks Fizz, are being challenged by their former colleague Bobby G – real name Robert Gubby – whose own group, Bucks Fizz, contains his wife Heidi Manton, who holds the copyright in the name. The three in turn are objecting to his use of the title.
Evidence from the competing claims were heard on Friday in Wales by Allan James, a principal hearing officer at the Intellectual Property Office.
The trio's solicitor, Dean Dunham, told the hearing there had been a verbal agreement between the two parties to use the different names, but Bucks Fizz fans had been disappointed to discover they had booked tickets for a band featuring only one member of the original lineup.
Aston started performing again with Baker and Nolan in 2009. Gubby said he felt entitled to claim his band was the original act because it had a "direct connection" to when it was first founded, adding that bands often had lineup changes throughout the years and this did not mean the public were being deceived.
Baker said: "Gubby has no right to stop us from working. We don't want it all but we do want our share.
"We've got an album that should have been released by now and we can't because of the dispute over the name, so it's affecting our livelihood."
James will be making his mind up within the next six weeks.
