For all those that missed the Sania Saeed and Fuzon breaking apart details..obviously the band broke apart because of her but here's a glimpse in "hidden" words.
Emu blamed it on bad record label deal and Shafqat. He claimed that Fuzon's manager Sen Management (Erum, Nazia and Sania Saeed) caused the rift. Sen Management, in Emu's words, was managing Shafqat more.
Back then, Shafqat didn't bring up breaking up or any problems within the band. His take was that an album deal was in the pipeline. But with three different opinions, the break up was inevitable.
And when the band broke up, Instep (along with the entire media brigade) received a press release that introduced Rameez Mukhtar as the new vocalist. The press release didn't even mention Shafqat or his reason for a departure.
