The Fratellis are all set for their first Glasgow gig in over three years at the O2 ABC next Wednesday, after taking a lengthy break because they were "fed-up".
But Jon, who went on to form Codeine Velvet Club and release a solo album, believes maybe a more direct solution might have helped.
"Some bands deal with their problems by punching each other, but we weren't those kind of guys, so we dealt with it by leaving each other alone for a while," he says.
"There was never a falling out, although maybe a better way of dealing with the slight fractures [in the group] would have been to have a scrap. We were completely fed-up as even married couples don't spend every night and day together, and if they do that's unhealthy.
"The way we got back together is the way we first stopped playing, as there was nothing too dramatic, we just stopped playing and talking to each other."
That was that, until Jon decided to e-mail bassist Barry and drummer Mince earlier this year, and ask if they fancied gigging again.
Two replies saying yes swiftly appeared in Jon's inbox, and The Fratellis were back together, playing a charity gig in Stirling and then plotting their autumn tour, which ends at the ABC.
The band's 2006 debut, Costello Music smashed the rowdy rockers into the charts with Chelsea Dagger proving a huge hit. Follow up Here We Stand wasn't as popular for the Glasgow lads, and Jon admits he struggled to cope with what The Fratellis' music should be.
"We got a bit fed-up as being pigeonholed as something that wasn't too serious," he says.
"Now I would just see it as a badge of honour, and thank God there was a band around that made people smile."
And while the trio will roll out all their hits next week, there will also be room for new songs, too "just so we make it clear that there will be some life after that gig," explains Jon.
He added: "A lot of what we're rehearsing are the old songs, ones we did around the pubs of Glasgow and got left behind."
"After the Glasgow gig we'll be going into the studio a few days to spend a week or so recording."
That background, playing pubs and tiny clubs around Glasgow, helped The Fratellis grow.
Jon believes the city inspired the band's songs, too, saying: "A band like us could only have been a Glasgow band, we wouldn't have worked anywhere else," he says.
He does seem to appreciate just how popular the trio were a few years ago.
