UB40 reignited a long-simmering feud with their former frontman as they announced a whirlwind Scottish tour.
The reggae stars revealed they will be performing at Perth Concert Hall later this year, complete with five of their founding members.
It comes less than two years after a very different looking UB40 headlined the Rewind Festival at Scone, with lead singer Ali Campbell knocking out hits like Red Red Wine and Kingston Town.
Ali walked out on the band in 2008 and now faces legal action from his former members for continuing to perform under the UB40 name.
UB40, the other one, claim that Ali is “hoodwinking” fans.
Ali’s brother Robin, who has been with the band since the start, said: “Ali has been shamelessly attempting to pass himself off as a ‘reformed’ UB40 which has confused many of our fans, the media and concert promoters all over the world.
“We’ve had to issue writs against Ali and two other former members.
“If they want to be UB40 so badly, they should never have chosen to leave UB40 in the first place.”
The line-up which will perform in Perth features brothers Robin and Duncan Campbell who joined the band after Ali’s exit as well as original members Earl Falconer, Norman Hassan, Jimmy Brown and Brian Travers.
UB40 formed in 1978 with the critically acclaimed debut album Signing Off.
The group has since had dozens of top 40 hits and has sold more than 100 million records.
The Perth gig, on May 6, will be part of the second leg of their Getting Over the Storm tour.
Aside from Motherwell, it is their only Scottish date.
Principal songwriter Travers said: “The success of the current tour has confirmed what we already knew, that it’s better to play to 100,000 people across 40 intimate venues across the whole of the country than playing to the same number of people at six enormous domes in the same cities.
“It’s a much better experience for both the band and our fans and we get to play in towns and cities we haven’t visited for many years.”
In an interview last year, Ali Campbell revealed he had not spoken to his former bandmates for several years and he had no intention of doing so “any time soon”.
FAMILY FEUDS
The bitter break-up of UB40 is, of course, not the only example of sibling rivalry in rock music.
The original warring brothers of pop were Don and Phil Everly better known as the Everly Brothers who effectively crossed each other off their
Christmas card lists in spectacular fashion at a gig in 1973.
During the show, Phil threw down his guitar and stormed off stage, leaving his brother to explain to the audience that the group was breaking up.
They did not play together again for another decade.
Brothers John and Tom Fogerty, of Creedence Clearwater Revival, stunned fans with a massive falling out at the height of their fame in the mid-70s.
Sadly, the pair never got the chance to reconcile their differences before Tom’s death, as a result of tuberculosis in 1990.
The Jesus and Mary Chain’s Jim and William Reid had a similar bust-up live on stage in Los Angeles, while American rockers the Black Crowes announced their split amid a rift between founding brothers Rich and Chris Robinson.
However, the kings of the sibling spats still remain Noel and Liam Gallagher of Oasis.
The Britpop icons were due to play Chelmsford’s V Festival in 2009, but cancelled at the last minute after a falling out to end all falling outs.
Noel later revealed they had squared off over Liam’s demands to include a free plug for his clothing range in their tour programme.
