The AMV act is about a couple's life in Mumbai, where the woman is not working but the guy is. The song is different, the concept is different - the couple is struggling to make ends meet, with only the guy working. In Shakti's act, the concept is about a working woman who is also a mother, and how much she has to do at home to get her kids ready for school in the morning, see them off to school, then leave for work, and meet all the demands and deadlines at work, while taking calls from her kid, and then get back home to make dinner for her family and then next day starts all over again that she even loses track of which day it is! Shakti's act song is from Chachi 420 and not from Dauda..
Anyway, Shakti's act was her own concept - Terence mentioned that after her act that day, that Shakti wanted to do an act for the working women in Mumbai and pay a tribute to them, and so the concept is of Shakti and it was great of Terence to acknowledge that.
