I had a vague suspicion Balki might do this, because of his obsession with old songs of IR. Maybe they dont want to take any 'risks' :-) . This is okay with me, as long as, the album is considered a hit and IR gets more chances in hindi. Hopefully, they new environment will inspire and challenge him, in future. I also have a feeling that Balki will 'product manage' the output very well and will make sure the style is acceptable to the north indian audience. He is after all a business savvy person.
