Trio Rough Copy went down to a duo for the second half of the tour's run earlier this year, put down to a 'backstage incident' at the time.
Band member Kazeem Ajobe was cut from the live arena show earlier leaving bandmates Sterling Ramsay and Joseph Thomas to conclude the remaining dates as a duo.
Speaking about the behind the scenes clash with Sam, Kazeem said: “It was a man-to-man bust-up that resulted in a bit of a scrapple and grapple.”
He told The Sun newspaper: “It was a bit WWE and like two lions in a den. There was something thrown, which should never have been.
“People were warned before it was thrown but it was ignored.”
Kazeem added: “He’s a good guy, but he’s very boisterous as well so he can be very irritable.”
The singer went on to insisted that there were no hard feelings between him and show bosses and he was now focused on continuing on as part of Rough Copy, who are now a trio once again.
“I served my punishment, which was very upsetting, but now we’re moving on to the future and continuing the journey as a trio," he told the tabloid this weekend.
