I also agree to your other observation on the 'Aao na gale lagaao na' song... Based on the standards that Sumitra had set earlier, it did not meet the expectations, but this rendition of hers was still lot better than Shrestha, Aisha and Meenal... The song is extremely difficult, and if one is not sure of doing it well - they should not sing such tough songs just for the heck of it!
I am also looking fwd to more such themes like Saturday... Really gives us the pleasure of listening to some great melodies...
